Sulfobridged polynuclear complexes of
platinum(II) and palladium(II)
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 mixed coordination of ligands
in the palladium complex. In the platinum(II) complex bidentate coordination of
ligands is realized through sulfur and nitrogen atoms.
Key words: 2-mercaptoethanol,
cysteamine, chelating, platinum and palladium complexes, mixed coordination,
bridge position.
