Abstract
When the platinum(II) and palladium(II) salts interact with ligands such as cystamine-(mercamine) HSCH2CH2NH2 and 2-mercaptoethanol HSCH2CH2OH under certain conditions, polynuclear complexes of the compositions are obtained: [Pt6(SCH2CH2NH2)8]Cl4. 5H2O and [Pd6(SCH2CH2OH)8]Cl4. In a comparative study of the IR and X-ray spectra of synthesized complexes and ligands, as well as the results of X-ray diffraction studies, it was established that sulfur atoms of 2-mercaptoethanol occupy a bridge position with a mixed coordination of ligands in the palladium complex. In the platinum(II) complex bidentate coordination of ligands is realized through sulfur and nitrogen atoms.
