Coordinatively unsaturated dithiophosphato complex [Cd((MeO)2PS2)2] (1) was reacted with the bifunctional ligands 3,5-di-(4-pyridyl)-1,2,4-thiadiazole (L1) and 3,5-di-(3-pyridyl)-1,2,4-thiadiazole (L2) to give the helicoidal coordination polymer (1·L1)∞ and the paddle-wheel dimer (1·L2)2, both characterised by single-crystal X-ray diffraction.

The configurational stability of these complexes, which in some cases is hampered by decomplexation and recomplexation of labile ligands, is achieved by the use of multidentate ligands in octahedral complexes, and of cyclopentadienyl anions (half sandwich complexes) in the case of tetrahedral structures.
