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