Abstract

The cyclometalated platinum complex [PtMe(bhq)(dppy)] (1), in which bhq = benzo{h}quinoline and dppy = 2-(diphenylphosphino)pyridine, was prepared by the reaction of [PtMe(SMe(2))(bhq)] with 1 equiv of dppy at room temperature. Complex 1 contains one free pyridyl unit and was readily characterized by multinuclear NMR spectroscopy and elemental microanalysis. The reaction of complex 1 with 1 equiv of [Ag(CH(3)CN)(4)]BF(4) gave the cyclometalated cluster complex [Pt(2)Me(2)(bhq)(2)(mu-dppy)(2)Ag(2)(mu-acetone)](BF(4))(2) (2) in 70% yield. The crystal structure of complex 2 was determined by X-ray crystallography, indicating a rare example of a butterfly cluster with a Pt(2)Ag(2) core in which the Ag atoms occupy the edge-sharing bond. In solution, the bridging acetone dissociates from the cluster complex 2, but as shown by NMR spectroscopy, the Pt(2)Ag(2) core is retained in solution and a dynamic equilibrium is suggested to be established between the planar and butterfly skeletal geometries.
