Preparation and crystal structure of binuclear chloro{6-[[chloro(triphenylphosphine)platinum](mesitylimino)methyl]pyridin-2-yl}bis(triphenylphosphine)platinum(II)

Treatment of pyridine-2,6-dicarboxyimidoyl dichloride with [Pt(PPh3)]4 afforded the novel platinacyclic compound (3). Molecular and crystal structures of the compound have been determined by single crystal X-ray diffraction technique.
