摘要：

Reaction of the tetranuclear compounds with bis(diphenylphosphino)methane gave the mononuclear complexes , with the diphosphine ligand binding in a monodentate fashion. Compounds are capable of bonding systematically to a second palladium atom through the noncoordinated phosphorus atom and the sulfur atom of the thiosemicarbazone moiety to give the dinuclear compounds , thus behaving as new bidentate P,S-metallo ligands. All of the compounds have been characterized by IR and NMR spectroscopy, and the molecular structure of has been determined by X-ray crystallography.
