A convenient route to dinuclear chloro-bridged platinum(ii) derivatives vianitrile complexes

Abstract

The syntheses of the complexes [PtCl₂(NCR)L] [R = Me, Et; L = PPh₃; R = Et, L = Py, CO] and [PtCl{(κ²-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(μ-Cl)ClL]₂. The crystal and molecular structures of cis-[PtCl₂(NCEt)(PPh₃)], [SP-4-2]-[PtCl{(κ²-P,C)P(OC₆H₄)(OPh)₂}(NCEt)] and trans-[Pt(μ-Cl){(κ²-P,C)P(OC₆H₄)(OPh)₂}]₂ are reported.
