Abstract

Mixed-ligand and mixed-metal trinuclear complexes bearing two {Pt-bisNHC-C1} moieties, [{Pt(bisNHC-C1)}(ML)(μ-S)] (ML = Pt(bisNHC-C2), = 2; ML = Pt(bisNHC-C3), = 2; ML = Rh(cod), = 1; ML = RhCp*, = 2), where bisNHC-C1, bisNHC-C2 and bisNHC-C3 represent methylene-, ethylene- and propylene-bridged bis-NHC ligands, respectively, were synthesised and structurally characterised. Reactions of these complexes with a half eq. of Ag(i) ions were examined using H and Pt NMR spectroscopy. The results exhibit that the trinuclear complexes react with Ag(i) ions accompanied by the formation of Ag-Pt bonds with the {Pt-bisNHC-C1} moieties in the first step affording corresponding heptanuclear complexes except for the RhCp* complex. The RhCp* complex gave a tetranuclear complex bearing the trinuclear unit with an Ag(i) ion. Further addition of Ag(i) ions for the other complexes resulted in disassembling of the heptanuclear clusters affording tetranuclear complexes confirmed by the observation of exchange of the Ag(i) ions in Pt NMR measurements, which exhibited signals with no coupling to Ag nuclei.

摘要

合成并对带有两个{Pt-双NHC-C1}部分的混合配体和混合金属三核配合物[{Pt(bisNHC-C1)}(ML)(μ-S)]（ML = Pt(bisNHC-C2)，= 2；ML = Pt(bisNHC-C3)，= 2；ML = Rh(cod)，= 1；ML = RhCp*，= 2）进行了结构表征，其中bisNHC-C1、bisNHC-C2和bisNHC-C3分别代表亚甲基桥连、亚乙基桥连和亚丙基桥连的双NHC配体。使用氢谱和铂谱核磁共振波谱研究了这些配合物与半当量银离子的反应。结果表明，除RhCp配合物外，三核配合物与银离子反应，第一步中与{Pt-双NHC-C1}部分形成Ag-Pt键，生成相应的七核配合物。RhCp配合物生成了一个带有银离子的三核单元的四核配合物。对其他配合物进一步添加银离子导致七核簇解体，通过铂谱核磁共振测量中银离子的交换观察证实生成了四核配合物，该测量显示的信号与银核无耦合。
