This thesis focuses on the study of hydrogen dynamic behavior in a series of proton sponge cations as well as in bis(silyl)hydride organometallic complexes. To understand the dynamic behavior, a new tool, i.e. the three-dimensional vibrational Schrödinger equation has been derived and solved. Three different vibrational patterns for hydrogen motion have been revealed. The classification of proton sponges and bis(silyl)hydride complexes into those with localized and delocalized hydrogen behavior has been proposed. For the organometallic complexes the influence of the vibrational motion of the hydrogen on J(Si−H) spin−spin coupling constants has been studied. Also this thesis presents a study of [Cp*Co(SiR3)2(H)2] cobalt complexes and their iridium analogues to detect possible Si···H interactions. Based on molecular geometries, Wiberg bond indices, and J(Si-H) spin-spin coupling constants, at least two residual Si···H interactions have been detected in cobalt complexes while there are ...

tats This invention relates to novel organometallic compounds and their preparation. More particularly, the present invention relates to novel and useful transition metal complexes of azulene. An object of this invention is to provide a novel class of organometallic compounds. Another object is to provide a class of stable transition metal coordination compounds of azulene. A further object is to provide a novel class of stable non-ionic azulene metal complexes having unsymmetric configurations. Other objects will become apparent from the specification and claims which follow. The above objects are accomplished by providing nonionic complex compounds of the metals of groups IVB- VIII in which a metal atom or atoms are bonded to azulene, which compound is stabilized by additional covalent bonding of the metal atom or atoms to dissimilar electron-donating groups.

The general name metallocene is derived from ferrocene, (C5H5)2Fe or Cp2Fe , systematically named bis(η5-cyclopentadienyl)iron(II). According to the IUPAC definition, a metallocene contains a transition metal and two cyclopentadienyl ligands coordinated in a sandwich structure, i. e., the two cyclopentadienyl anions are co-planar with equal bond lengths and strengths. Using the nomenclature of "hapticity", the equivalent bonding of all 5 carbon atoms of a cyclopentadienyl ring is denoted as η5, pronounced "pentahapto." There are exceptions, such as uranocene, which has two cyclooctatetraene rings sandwiching a uranium atom.. In metallocene names, the prefix before the -ocene ending indicates what metallic element is between the Cp groups. For example in ferrocene, iron(II) or ferrous is present.. In contrast to the more strict definition proposed by IUPAC, which requires a d-block metal and a sandwich structure, the term metallocene and thus the denotation -ocene, is applied in the chemical ...
f-Block Metallocene refers to a class of organometallic sandwich compounds with f-Block metal and electron-rich ligands like cyclopentadienyl anion. The first prepared and well-characterized f-block metallocenes were the tris(cyclopentadienyl) lanthanide complexes, (C5H5)3Ln (Ln = La, Ce, Pr, Nd, Sm and Gd). However, their significance is limited more to their existences and structures than to their reactivity. The cyclopentadienyl ligands of f-block metallocenes were considered as inert ancillary ligands, only capable of enhancing their stability and solubility, but not their reactivity. In addition, only late and small metals in the lanthanide series, i.e., elements from Sm to Lu, are trivalent metallocene complexes, [(C5H5)2LnZ]n In 1980, the pentamethylcyclopentadienyl ligand, C5Me− 5, was introduced to prepare the lanthanide complexes with all metals in the series. Apart from improving the stability and solubility of the complexes, it was demonstrated to participate in organometallic ...

A bulky, optically active monoanionic scorpionate ligand, tris(4S-isopropyl-5,5-dimethyl-2-oxazolinyl)phenylborate (To P*), is synthesized from the naturally occurring amino acid l-valine as its lithium salt, Li[To P*] (1). That compound is readily converted to the thallium complex Tl[To P*] (2) and to the acid derivative H[To P*] (3). Group 7 tricarbonyl complexes To P*M(CO) 3 (M = Mn (4), Re (5)) are synthesized by the reaction of MBr(CO) 5 and Li[To P*] and are crystallographically characterized. The ν CO bands in their infrared spectra indicate that π back-donation in the rhenium compounds is greater with To P* than with non-methylated tris(4S-isopropyl-2-oxazolinyl)phenylborate (To P). The reaction of H[To P*] and ZnEt 2 gives To P*ZnEt (6), while To P*ZnCl (7) is synthesized from Li[To P*] and ZnCl 2. The reaction of To P*ZnCl and KOtBu followed by addition of PhSiH 3 provides the zinc hydride complex To P*ZnH (8). In this study, compound 8 is the first example of a crystallographically ...

A carbon ignition temperature depressing agent is disclosed along with a method of regenerating an automotive particulate trap using the ignition temperature depressing agent. The agent is effective to promote oxidation of on-board collected carbonaceous particles extracted from the automobile exhaust. The agent comprises (a) an organometallic compound that upon heating (the combustion process of the engine) forms a readily reducible metal oxide which when finely divided promotes a carbonaceous ignition temperature in the range of as low as 450 F. and up to as low as 675 F., and (b) an aerosol-promoting liquid carrier effective to form a fine mist with the organometallic compound when sprayed, the carrier having a boiling point in the range of 176 -302 F. (80 -150 C.). The organometallic compound is one or more metal octoates having the metal selected from the group consisting of copper, nickel and cerium. The organometallic compounds are readily soluble and stable in the fuel supply used with an
Organometallic chemistry, rigorously defined by the chemical synthesis and reactivity of molecules with metal-carbon bonds, is a vibrant area of research with a large variety of practical applications [1]. For example, organometallic complexes are commonly used as catalysts for the production of commodity chemicals, materials such as polymers, and in fine chemical synthesis and medicinal chemistry discovery [1,2]. The majority of discoveries in the area have been performed in the solution phase, with studies in the solid state generally often reserved only for structural analysis; for example, single-crystal X-ray crystallography and, to a significantly lesser extent, solid-state nuclear magnetic resonance spectroscopy. By contrast to the solution phase, studies on the synthesis of, and catalysis using, organometallic complexes in the solid phase have attracted significantly less attention, even though there are potential benefits to this approach, such as: improved selectivities in synthesis ...

The three organometallic complexes [(Cis-Pt^II (DDH) (2,5- Dihidroxibenzensulfonic)^2, Rh^I (CO)2 Cl(2- Aminobenzothiazole) and Rh^I (CO)2 Cl(5-Cl-2- Methilbenzothiazole)] used in this study had been previously found to have a high in vitro activity against promastigote and amastigote like forms of Leishmania donovani. Here, the cytotoxic effect of these new organometallic complexes on the J-774 macrophages were studied. Only the Rh^I(CO)2 Cl (2-Aminobenzothiazole) complex induced substantial toxicity in the cells.. Also, we assayed the effect of this complex on the parasite s biosynthesis of macromolecules. The Rh^I(CO)2Cl (5-Cl-2- Methylbenzothiazole) complex inhibited DNA, RNA, and protein synthesis. On the other hand, the two other compounds tested did not inhibit the incorporation of radioactive precursors. Finally important ultrastructural alterations in the parasites treated with the two non-cytotoxic complexes were observed ...

Nickelocene is the organonickel compound with the formula Ni(η5-C5H5)2. Also known as bis(cyclopentadienyl)nickel or NiCp2, this bright green paramagnetic solid is of enduring academic interest, although it does not yet have any known practical applications. Ni(C5H5)2 belongs to a group of organometallic compounds called metallocenes. Metallocenes usually adopt structures in which a metal ion is sandwiched between two parallel cyclopentadienyl (Cp) rings. In the solid-state, the molecule has D5h symmetry, wherein the two rings are eclipsed. The Ni center has a formal +2 charge, and the Cp rings are usually assigned as cyclopentadienyl anions (Cp−), related to cyclopentadiene by deprotonation. The structure is similar to ferrocene. In terms of its electronic structure, three pairs of d electrons on nickel are allocated to the three d orbitals involved in Ni-Cp bonding: dxy, dx2-y2, dz2. One of the two remaining d-electrons resides in each of the dyz and dxz orbitals, giving rise to the ...

The chelates were introduced and assembled through reductive amination starting from 3-O-1,2;5,6-di-O-isopropylidene-alpha-D-glucofuranose]-acetaldehyde. After deprotection, the pyranose derivatives were reacted with the precursor NEt4](2)ReBr3(CO)(3)] to afford the corresponding organometallic complexes in yields between 54% and 94%. The NMR, MS, and IR analyses corroborated the tridentate coordination of the organometallic metal center exclusively via the synthetic chelates. In the case of the N-(acetyl)picolylamine derivative, the coordinative properties were further confirmed by X-ray structure analysis of the first Re(CO)(3)-D-glucofuranose complex. All glucose complexes unveiled good stability and ...

This thesis sets out to explore the electronic structures and redox properties of organometallic complexes. The mixed valence states of these complexes have been investigated and classified. Chapter 1 introduces the general area and provides a brief summary of the theory to electron transfer. The concepts discussed in Chapter 1 are developed further in subsequent Chapters. A trimetallic molecular assembly featuring two redox-active organoiron fragments connected via a central ruthenium tetramesitylporphyrin socket through pendant pyridyl moieties was investigated using electrochemical and UV-vis-NIR/IR spectroelectrochemical studies. Electrochemical studies reveal three reversible oxidation waves, the first two of which can be attributed to the stepwise oxidation of the iron centres. The redox separation between these iron redox waves was found to be constant regardless of electrolyte composition, suggesting a "through bond" mechanism for electronic interactions between the iron centres. An ...
The use of transition organometallic complexes as reagents for the synthesis of complex organic molecules has been under intensive growth and development for several decades, and many organic transformations of profound synthetic potential has been achieved. Particularly, the use of organoiron complexes has been recognized as a powerful tool in the synthetic methodology due to their ability to react with nucleophiles and electrophiles in a stereoselective fashion. The use of NMO as a chemoselective, metal mediated oxidizing agent will be discussed.

Static solid-state 35Cl (I = 3/2) NMR spectra of the organometallic compounds Cp2TiCl2, CpTiCl3, Cp2ZrCl2, Cp2HfCl2, Cp*2ZrCl2, CpZrCl3, Cp*ZrCl3, Cp2ZrMeCl, (Cp2ZrCl)2μ-O, and Cp2ZrHCl (Schwartzs reagent) have been acquired at 9.4 T with the quadrupolar Carr−Purcell Meiboom−Gill (QCPMG) sequence in a piecewise manner. Spectra of several samples have also been acquired at 21.1 T. The electric field gradient (EFG) tensor parameters, the quadrupolar coupling constant (CQ) and quadrupolar asymmetry parameter (ηQ), are readily extracted from analytical simulations of the spectra. The 35Cl EFG and chemical-shift tensor parameters are demonstrated to be sensitive probes of metallocene structure and allow for differentiation of monomeric and oligomeric structures. First-principles calculations of the 35Cl EFG parameters successfully reproduce the experimental values and trends. The origin of the observed values of CQ(35Cl) are further examined with natural localized molecular orbital (NLMO) ...

Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant specialist fields, the series creates a unique service for the active research chemist with regular critical in-depth accounts of progress in particular areas of chemistry. Historically, The Royal Society of Chemistry and its predecessor, The Chemical Society, have published reports of developments in chemistry since the end of the 19th century. By 1967 however, the sheer volume of chemistry published had become so great that it was decided to split the research into specialist areas, and the series Specialist Periodical Reports was born. Current subject areas covered are Amino Acids, Peptides and Proteins. Carbohydrate Chemistry, Catalysis, Electron Spin Resonance, Nuclear Magnetic Resonance, Organometallic Chemistry. Organophosphorus Chemistry, Photochemistry and Spectroscopic Properties of Inorganic and Organometallic Compounds.
Organic compounds can also be classified or subdivided by the presence of heteroatoms, e.g., organometallic compounds, which feature bonds between carbon and a metal, and organophosphorus compounds, which feature bonds between carbon and a phosphorus.
