A convenient route to dinuclear chloro-bridged platinum(II) derivatives via nitrile complexes

The syntheses of the complexes [PtCl2(NCR)L] [R = Me, Et; L = PPh3; R = Et, L = Py, CO] and [PtCl{(kappa(2)-P,C)P(OC6H4)(OPh)(2)}(NCEt)] are described starting from the easily available [PtCl2(NCR) 2]. The stability of the products under different experimental conditions is discussed as well as their use as precursors to dinuclear complexes [Pt(mu-Cl)ClL](2). The crystal and molecular structures of cis-[PtCl2(NCEt)(PPh3)], [SP-4-2]-[PtCl{(kappa(2)-P,C) P(OC6H4)(OPh)(2)}(NCEt)] and trans-[Pt(mu-Cl){(kappa(2)-P,C)P(OC6H4)(OPh)(2)}](2) are reported.
