Dithiocarbamate complexes of rhodium (III), iridium (III), palladium (II) and platinum (II)

We report the preparation and characterization of the complexes of rhodium(III), iridium(III), palladium(II) and platinum(II) with the following ligands: Pzdtc, N-MePzdtc, N-PhPzdtc, Pipdtc, 4- PhPipdtc, Morphdtc, Timdtc, and with their methyl esters.The dithio ligands act as bidentate S,S′-donors in all the new derivatives. From the electronic absorption spectra the values of the ligand field parameters were determined. The nephelauxetic parameters are indicative of a strong covalency in the metal-ligand bond. All the compounds reported here are diamagnetic
