Neutral or negatively charged ligands bonded to metal cations or neutral atoms. The number of ligand atoms to which the metal center is directly bonded is the metal cation's coordination number, and this number is always greater than the regular valence or oxidation number of the metal. A coordination complex can be negative, neutral, or positively charged.

Coordination Chemistry - Twenty One by fra International Conference on Coordination Chemistry 1980 Toulouse; 2 editions; First published in 1981
Coordination complexes are so pervasive that their structures and reactions are described in many ways, sometimes confusingly. The atom within a ligand that is bonded to the central metal atom or ion is called the donor atom. In a typical complex, a metal ion is bonded to several donor atoms, which can be the same or different. A polydentate (multiple bonded) ligand is a molecule or ion that bonds to the central atom through several of the ligands atoms; ligands with 2, 3, 4 or even 6 bonds to the central atom are common. These complexes are called chelate complexes; the formation of such complexes is called chelation, complexation, and coordination. The central atom or ion, together with all ligands, comprise the coordination sphere.[5][6] The central atoms or ion and the donor atoms comprise the first coordination sphere. Coordination refers to the coordinate covalent bonds (dipolar bonds) between the ligands and the central atom. Originally, a complex implied a reversible association of ...
This thesis describes the synthesis and characterisation of novel complexes bearing monoanionic phenolateamine ligands and explores their catalytic behaviour in the ring opening polymerisation of lactide and in the polymerisation of ethylene. Chapter 1 introduces and reviews various aspects of the coordination chemistry of phenolateamine ligands and is followed by an introduction to the field of lactide polymerisation. Chapter 2 describes the preparation of several potentially tetradentate proligands via the Mannich reaction. The ligands presented have various combinations of donors, chain length and substituents on the phenyl backbone. The synthesis and characterisation of several novel main group complexes (K, Ca and Al) using these ligands is presented. The calcium bis-chelate complexes are shown to be highly active in the ring opening polymerisation of lactide. Chapter 3 introduces a new family of zinc species stabilised by these ligands. The coordination chemistry of zinc alkyls and ...

In coordination chemistry, a structure is first described by its coordination number, the number of ligands attached to the metal (more specifically, the number of donor atoms). Usually one can count the ligands attached, but sometimes even the counting can become ambiguous. Coordination numbers are normally between two and nine, but large numbers of ligands are not uncommon for the lanthanides and actinides. The number of bonds depends on the size, charge, and electron configuration of the metal ion and the ligands. Metal ions may have more than one coordination number. Typically the chemistry of transition metal complexes is dominated by interactions between s and p molecular orbitals of the donor-atoms in the ligands and the d orbitals of the metal ions. The s, p, and d orbitals of the metal can accommodate 18 electrons (see 18-Electron rule). The maximum coordination number for a certain metal is thus related to the electronic configuration of the metal ion (to be more specific, the number ...

Coordination chemistry, as we know it today, has been shaped by major figures from the past, one of whom was Joseph Chatt. Beginning with a description of Chatts career presented by co-workers, contemporaries and students, this fascinating book then goes on to show how many of todays leading practitioners in the field, working in such diverse areas as phosphines, hydrogen complexes, transition metal complexes and nitrogen fixation, have been influenced by Chatt. The reader is then brought right up-to-date with the inclusion of some of the latest research on these topics, all of which serves to underline Chatts continuing legacy. Intended as a permanent record of Chatts life, work and influence, this book will be of interest to lecturers, graduate students, researchers and science historians.

Here we report the syntheses and crystal structures of a series of cobalt(II) and nickel(II) complexes derived from RNP2 ligands (where R = OMeBz, HBz, BrBz, Ph) bearing ethylene linkers between a single N and two P donors. The CoII complexes generally adopt a tetrahedral configuration of general formula [(NP2)Co(I) 2], wherein the two phosphorus donors are bound to the metal center but the central N-donor remains unbound. We have found one case of structural isomerism within a single crystal structure. The CoII complex derived from BzNP2 displays dual coordination modes: one in the tetrahedral complex [(BzNP2)Co(I)2]; and the other in a square pyramidal variant, [(BzNP2)Co(I)2]. In contrast, the NiII complexes adopt a square planar geometry in which the P(Et)N(Et)P donors in the ligand backbone are coordinated to the metal center, resulting in cationic species of formula [(RNP2)Ni(I)]+ with iodide as counterion. All NiII complexes exhibit sharp 1H and 31P spectra in the diamagnetic region. The Co II

N-Heterocyclic carbenes are now commonly encountered in organometallic and inorganic coordination chemistry. The increasing attention they enjoy is due to their ability to act as ancillary ligands in a growing number of transition metal catalysts or even to play the role of nucleophilic reagents and catalysts in diverse organic transformations. As a fine addition to the NHC-Ru-alkylidenes, popular for their tremendous success in metathesis chemistry, an array of robust and stable Ru-NHCs has proven their utility in non-metathetical reactions. The present review surveys different classes of Ru-NHCs and their applications as efficient catalysts (or precatalysts) in several types of fundamental organic processes e.g. ...

Inorganic oxides possess a remarkable diversity of chemical composition and architecture, giving rise to a vast domain of solid state properties with applications ranging from heavy construction to molecular electronics. Despite such inherent fundamental and practical significance, their structural design, in the sense of controlled synthesis of metastable but persistent extended structures, remains a challenge in solid state chemistry. It is also noteworthy that, while some naturally occurring oxide minerals possess complex crystal structures, the majority are of simple composition and have highly symmetrical structures with rather small unit cells. Although such simple oxides can possess unique and specific properties, such as piezoelectricity, ferromagnetism or catalytic activity, as a general rule there is a correlation between the complexity of the structure of a material and its functionality. However, the occurrence of complex inorganic oxides in the geosphere and the biosphere suggests ...

The catalytic triad residues, i.e Asp 97, Asp 188 and Glu 326, are known as the DDE motif and therefore are conserved amid Tnps and retroviral INs. For HIV 1 IN, the DDE motif is comprised of Asp 64, Asp 116 and Glu 152. It really is believed that these three residues would presume a equivalent spatial arrangement because the corresponding ones in Tn5 Tnp. As unveiled from readily available X ray structures with the HIV one IN core domain, Asp 64 and Asp 116 form a coordination complex with a single Mg2 . It has been proposed that a second Mg2 is usually most likely chelated by Glu 152 and Asp 64 once HIV one IN binds its DNA substrate. As towards the metal ions, it is actually frequently accepted that Mg2 can be a alot more sensible cofactor for integration in cells. Based upon these details, we chose to utilize the DDE motif of Tn5 Tnp as the template to partly mimic the binding web page of IN and then explore how the IN inhibitors chelate the Mg2 as a result of use of B3LYP density practical ...

Many thiol-containing molecules show heavy metal complexation ability and are used as antidotes. In this study, the potential function associated with thiol-containing peptides (TCPs) from soy protein hydrolysates as natural detoxicants for heavy metals is reported. TCPs enriched by Thiopropyl-Sepharose 6B covalent chromatography had different molecular weight distributions as well as different numbers of proton dissociable groups, depending on the proteases and degree of hydrolysis. The major contribution of sulfhydryl groups was confirmed by the largest pH decrease between 8.0 and 8.5 of the pH titration curves. The complexation of TCPs with heavy metals was evaluated by stability constants (βn) of TCP-metal complexes whose stoichiometry was found to be 1:1 (ML) and 1:2 (ML2). TCPs from degree of hydrolysis of 25% hydrolysates gave high affinities towards Hg2+, Cd2+, and Pb2+ (giving similar or even bigger lgβ values than that of glutathione). A significantly positive correlation was found between

I cant figure out how to determine the electron count for these rhodium complexes. Starting with the one at the top. Heres how I count its electrons: rhodium is a group 9 element so it has 2s electrons and 7d electrons which means it has 9 out of 18 valence electrons to begin with. The 2 CO ligands add an extra 4 electrons, bringing the total to 13. Im a bit confused about how the iodide ligands work, do they also donate 2 electrons each? If so, that brings the electron count to 17. The ion has a charge of -1, bringing the total electron count to 18. How can this be a coordinatively unsaturated complex? If you add 2 more ligands to it then you end up with an electron count of 22 ...

Since the discovery of cisplatin about 40 years ago, the design of innovative metal-based anticancer drugs is a growing area of research. Metal elements offer specific characteristics due to their intrinsic properties and could be used in relation to their final state: a metal complex, a radionuclide, a metal-based nanoparticle product. Transition metal coordination complexes interact with cell molecular targets, affecting biochemical functions resulting in cancer cell destruction. Radionuclides are another way to use metals as anticancer therapy. The metal nucleus of the unstable radionuclide becomes stable by emitting energy. The biological effect in different tissues is obtained by the absorption of this energy from the radiation emitted by the radionuclide, the principal target generally agreed for ionizing radiations being DNA. A new area of clinical research is now emerging using the same experimental metal elements, but in a radically different manner: metals and metal oxides used as ...

DNA has a strong affinity for many heterocyclic aromatic dyes, such as acridine and its derivatives. Lerman in 1961 first proposed intercalation as the source of this affinity, and this mode of DNA binding has since attracted considerable research scrutiny. Organic intercalators can inhibit nucleic acid synthesis in vivo, and they are now common anticancer drugs in clinical therapy.. The covalent attachment of organic intercalators to transition metal coordination complexes, yielding metallointercalators, can lead to novel DNA interactions that influence biological activity. Metal complexes with σ-bonded aromatic side arms can act as dual-function complexes: they bind to DNA both by metal coordination and through intercalation of the attached aromatic ligand. These aromatic side arms introduce new modes of DNA binding, involving mutual interactions of functional groups held in close proximity. The biological activity of both cis- and trans-diamine PtII complexes is dramatically enhanced by the ...

Learning, knowledge, research, insight: welcome to the world of UBC Library, the second-largest academic research library in Canada.
Few would say that the construction of multiple nano-engineered cavities for the immobilization of catalytically active transition metals was a non-trivial task. We are talking clever technology here. And appropriately perhaps, such is the domain of Junior Professor Dr. Guido Clever (of the Inorganic Chemistry Dept., Göttingen University, Germany) who has his own laboratory at the university, aptly named The Clever Lab.. Heres a graphic example of the labs work :. ...
A well-defined amphiphilic core-shell polymer functionalized with bis(p-methoxy-phenylphosphino)phenylphosphine (BMOPPP) in the nanogel (NG) core has been obtained by a convergent RAFT polymerization in emulsion. This [email protected] and the previously-reported [email protected] (TPP = triphenylphosphine) and core cross-linked micelles ([email protected]; L = TPP, BMOPPP) having a slightly different architecture were loaded with [Rh(acac)(CO)2] or [RhCl(COD)]2 to yield [Rh(acac)(CO)([email protected])] or [RhCl(COD)([email protected])] (Pol = CCM, NG). The interparticle metal migration from [Rh(acac)(CO)([email protected])] to [email protected] is fast at natural pH and much slower at high pH, the rate not depending significantly on the polymer architecture (CCM vs. NG). The cross-exchange using [Rh(acac)(CO)([email protected])] and [RhCl(COD)([email protected])] (Pol = CCM or NG) as reagents at natural pH is also rapid (ca. 1 h), although slower than the equivalent homogeneous reaction on the molecular species (<5 min). On the other hand, the subsequent rearrangement of [Rh(acac)(CO)(TPP

Reaction of the Ir(I)-Xantphos complex [Ir(kappa(2)-Xantphos)(COD)][BAr(4)(F)] (Xantphos - 4,5-bis(diphenyl-phosphino)-9,9-dimethylxanthene, Ar(F) = C(6)H(3)(CF(3))(2)) with H(2) in acetone or CH(2)Cl(2)/ MeCN affords the Ir(III)-hydrido complexes [Ir(kappa(3)-Xantphos)(H)(2)(L)][BAr(4)(F)], L = acetone or MeCN, whereas in non-coordinating CH(2)Cl(2) solvent dimeric [Ir(kappa(3)-Xantphos)(H)(mu-H)](2)[BAr(4)(F)](2) is formed. A common intermediate in these reactions that invokes a (sigma, eta(2)-C(8)H(13)) ligand is reported. Addition of excess tert-butylethene (tbe) to [Ir(kappa(3)-Xantphos)(H)(2)(MeCN)][BAr(4)(F)] results in insertion of a hydride into the alkene to form [Ir(kappa(3)-Xantphos)(MeCN)(CH(2)CH(2)C(CH(3))(3))(H)][BAr(4)(F)], an Ir(III) alkyl-hydrido-Xantphos complex. This reaction is reversible, and heating (80 degrees C) results in the reformation of [Ir(kappa(3)-Xantphos)(H)(2)(MeCN)][BAr(4)(F)] and tbe. These complexes have been characterised by NMR spectroscopy, ESI-MS and ...
This project focuses on the design and synthesis of coordination complexes as models for the artificial nucleases, superoxide dismutases and molybdenum/iron-related enzymes. The research includes (1) design and construction of a series of Ru(II)-polypyridyl complexes and explore their properties of DNA binding and cleavage, as well as their selectivity and efficiency of DNA recognition. The structures of these complexes will be systematically tuned by varying the shapes of the intercalative ligands, which will enable us to study the mechanism for the interactions between the complexes and DNA. This research will lay foundation for the development of new DNA molecular probes and therapeutic reagents. (2) Based on the structures of the active centers of some metal enzymes, several metal complexes with cyclodextrin or biologically related ligands will be prepare as model compounds for metalloenzymes such as metallohydrolase and superoxide dismutase. Their structures will be fully studied and their ...
There are two main areas of research being pursued at present: (i) coordination chemistry of new multidentate mixed-donor ancillary ligands, and (ii) activation and functionalization of molecular nitrogen.. Because the reactivity of a metal complex can be fine-tuned by the ligands that surround the metal, it becomes important to examine new kinds of ligands and ligand combinations. Our tridentate ancillary ligand (PNP) incorporates both the hard amide donor and the soft phosphine ligand to generate a unique environment capable of binding to most elements in the periodic table. We have expanded the scope of this combination of nitrogen and phosphorus-containing ligands by preparing a macrocyclic version (P2N2) and a variety of other tridentate systems. Because of the backbone flexibility and the variations possible in substituents, these donor combinations allow us to modulate the metal complexs reactivity and examine these systems in the catalytic mode. As all of this research involves the ...
This thesis, entitled Anion Templated Self-Assembly - From Anion Complexes to the Formation of Supramolecular 2D Networks covers the anion complexation and ATSA abilities of different sets of ligands. The work will be divided into five chapters, gathering the work on each different sets of ligands separately. Chapter 1 will introduce the most recent advances in anion complexation and aniontemplated self-assembly, from the formation of 1:1 (Ligand:Anion) complexes to the formation of higher order bundles. Particular focus will be given to the use hydrogen bonding as the main interaction for the formation of anion-templated self-assemblies. Chapter 2, will discuss the synthesis and anion binding studies of tripodal tris(urea) ligands with Cl - , CH 3 COO - , H 2 PO 4 - and SO 4 2- . The anion binding studies carried out in solution on these ligands indicated that ATSA was occurring which lead us to investigate also the self-assembly behaviour in solution and in the solid state, wh... ...

N2 - Biliverdin (BV), a product of heme catabolism, is known to interact with transition metals, but the details of such interactions under physiological conditions are scarce. Herein, we examined coordinate/redox interactions of BV with Cu 2+ in phosphate buffer at pH 7.4, using spectrophotometry, HESI-MS, Raman spectroscopy, 1 H NMR, EPR, fluorimetry, and electrochemical methods. BV formed a stable coordination complex with copper in 1:1 stoichiometry. The structure of BV was more planar and energetically stable in the complex. The complex showed strong paramagnetic effects that were attributed to an unpaired delocalized e - . The delocalized ...
The concept of Stabilization can have two meanings with respect to polymer interactions with metal ions: Colloidal Stabilization is where precipitation in a fluid (water) occurs but the polymer prevents agglomeration of particles beyond 1 micron in size. These particles are thus stabilized via electrostatic interactions with the polymer and remain suspended throughout the water phase. These sub-micron particles are typically not visible to the naked eye. A notable exception to this is stabilized iron particles which can be visible due to the orange-brown color associated with most oxidized (Fe3+) iron complexes. The term Stabilization can also be a synonym for sequestration where a coordination complex between the polymer and soluble ions or surface interaction between the polymer and forming crystal lattices occurs and prevention of precipitation is achieved. In this case, threshold inhibition is not the prevailing mechanism since stoichiometry is undefined. INITIA™ Polymer Additives are ...

The macrobicyclic mixed-donor N3S3 cage ligand AMME-N(3)S(3)sar (1-methyl-8-amino-3,13,16-trithia-6,10,19-triazabicyclo[6.6.6]eicosane) can form complexes with Cu(II) in which it acts as hexadentate (N3S3) or tetradentate (N2S2) donor. These two complexes are in equilibrium that is strongly influenced by the presence of halide ions (Br- and Cl-) and the nature of the solvent (DMSO, MeCN, and H2O). In the absence of halides the hexadentate coordination mode of the ligand is preferred and the encapsulated complex (Cu-in(2+)) is formed. Addition of halide ions in organic solvents (DMSO or MeCN) leads to the tetradentate complex (Cu-out(+)) in a polyphasic kinetic process, but no Cu-out(+) complex is formed when the reaction is performed in water. Here we applied density functional theory calculations to study the mechanism of this interconversion as well as to understand the changes in the reactivity associated with the presence of water. Calculations were performed at the B3LYP/(SDD,6-31G**) ...

Life on earth essentially depends on the functioning of biological macromolecules such as proteins. At least 50 % of all known enzymes contain metal atoms as key constituents of their active sites, which are crucially for the reactivity. These metal centers often are chemically complex and involved in electron and proton transfer processes, substrate turnover, and regulation. A particular important aspect in biophysics research is the activation of small molecules at protein-bound metal centers with outstanding relevance in chemistry, medicine, industry, and energy applications. The field is still under rapid development. The lecture is addressed to advanced students with interests in biophysics. Covered topics include, e.g., coordination chemistry, assembly, molecular and electronic structure, photoreactions, redox processes, catalysis, and dynamics of metal centers in, for example, hydrogenase, photosystem, oxidase proteins. Selected experimental and theoretical approaches to understand the ...

In coordination chemistry and catalysis hemilability (hemi - half, lability - a susceptibility to change) refers to a property of many polydentate ligands which contain at least two electronically different coordinating groups, such as hard and soft donors. These hybrid or heteroditopic ligands form complexes where one coordinating group is easily displaced from the metal centre while the other group remains firmly bound; a behaviour which has been found to increase the reactivity of catalysts when compared to the use of more traditional ligands. In general, catalytic cycles can be divided into 3 stages: Coordination of the starting material(s) Catalytic transformation of the starting material(s) to the product(s) Displacement of the product(s) to regain the catalyst (or pre-catalyst) Traditionally the focus of catalytic research has been on the reaction taking place in the second stage, however there will be energy changes associated with the beginning and end steps due to their effect on the ...
