The cyclometalated heterobinuclear platinum-gold complexes [PtMe(bhq)(dppy)AuCl], 2, and [PtMe(bhq)(dppy)Au(NHC1)] PF6, 3, in which bhq= benzo{h}quinoline, dppy = 2-diphenylphosphinopyridine and NHC1 = 1,3-dimethylimidazol-2-ylidine have been prepared by reaction of the cyclometalated platinum complex [PtMe(bhq)(dppy)], 1, with 1 equivalent of AuCl(SMe2) or 1 equivalent of [Au(NHC1)]+ (prepared from ClAu(NHC1) and AgPF6), respectively. Complexes 2 and 3 were fully characterized using multinuclear NMR spectroscopy (1H, 31P). However complex 2was further characterized by x-ray crystallography, crystallization of complex 3 leads to form anew dimer complex 4,[Pt2(bhq)2(-dppy)2]2(PF6)2. The NMR ...
