半夹心结构有机金属铱和铑化合物Cp*M(TmMe)Cl(M=Ir,Rh;TmMe=三(2-巯基-1-甲基咪唑)硼酸根)的合成与表征

摘要

三齿配体三(2-巯基-1-甲基咪唑)硼酸盐[TmMe]K与含有半夹心结构金属铱和铑化合物[Cp*Ir(μ-Cl)Cl]2和[Cp*Rh(μ-Cl)Cl]2反应形成具有18电子结构的配合物[Cp*Ir(TmMe)]Cl(1)和[Cp*Rh(TmMe)]Cl(2).所有的化合物都经过IR,NMR和EA表征,并通过X-射线衍射单晶结构分析测定了配合物2的分子结构.%The reactions of [Cp*Ir(μ-Cl)Cl]2or[Cp*Rh(μ-Cl)Cl]2 with tripodal ligand tris (2-mercapto-1-methylimidazolyl) borate ([TmMe]K) lead to formation of the 18-electron complexes [Cp*Ir(TmMe)]Cl(1) and [Cp*Rh(TmMe)]Cl(2).Both complexes have been fully characterized by IR and NMR spectroscopy,as well as elemental analysis.The molecular structures of 2 have been confmned by X-ray crystal structure analysis.CCDC: 692299,2.
