Polynuclear Platinum (II) and Palladium (II) Complexes with a Bio-Logically Active Ligand

The interaction of platinum (II) and palladium (II) salts under certain conditions with such ligands as cysteamine- (mercamine) HSCH2CH2NH2 and 2-mercaptoethanol - HSCH2CH2OH results in the formation of polynuclear complexes: [Pt6(SCH2CH2NH2)8]Cl4, [Pd6)8]Cl4·5H2O, [Pd6(SCH2CH2OH)12]Cl4·3H2O and [Pt6(NH2CH2CH2S)8]Cl4·3H2O. Based on a comparison of the IR and X-ray spectra of the synthesized complexes and ligands, as well as the X-ray results, it was found that in palladium (II) complex sulfur atoms of 2-mercaptoethanol occupy a bridging position with a displaced coordination of ligands. In the platinum (II) complexes, the bidentate coordination of ligands with sulfur and nitrogen atoms is realized. The synthesized complexes in spite of having the same compositions but differ greatly in structure.
