Cl; Y = Cl, H or Me) have been prepared and characterized. Reaction of PtMe2(ER3)L with HCl yields PtMeCl(ER3)L, in exclusively one of three possible isomeric forms. Excess tetramethyltin reacts with Pt2Cl2(μ-Cl)2(PMe2Ph)2 giving both cis and trans Pt2(μ-Cl)2(PMe2Ph)2, as identified from the NMR spectra. Cleavage of Pt2(μ-Cl)2Me2(PMe2Ph)2 with donor ligands such as AsPh3, PMe2 or pyridine, was useful
