The complexes of palladium(II) and platinum(ll) with triphenylphosphine sulphide (Ph₃PS) and triphenylstibine (Ph₃Sb) of composition [ML₂X₂] (M = Pd^II, Pt^II ; L = Ph₃PS or Ph₃Sb and X = CI, Br, I or SCN) have been prepared and characterized. The triphenylstibine sulphide complexes like former ligand could not be isolated as the ligand get desulphurized in aqueous medium and the complexes of desulphurized ligand triphenylstibine have only been isolated in pure form. The complexes have been characterized by UV, IR, ¹H NMR spectroscopic methods and resembles with square planar geometry.
