Binuclear dimethylplatinum (II) complexes each containing monodentate phosphine ligands and a bridging diphosphine ligand X(PPh2)2, X = CH2 or NH. Molecular structure of cis,cis-[Me2(pyPh2P)Pt(μ-Ph2PNHPPh2)Pt(PPh2py) Me2] · 2CH2Cl2

A series of unusual organodiplatinum(II) complexes in which the dinuclear integrity is held by only one bridging ligand X(PPh2)2 with no metal-metal bonding has been prepared by a general route.
