摘　　要：合成了一系列含N-杂环卡宾二硫化碳加合物配体的锰铼金属有机化合物,其中包括3种单核化合物和3种双核化合物,对它们的结构进行了表征,并研究其反应性和电化学性质.与三烷基膦二硫化碳配体相比,含N-杂环卡宾二硫化碳加合物配体的锰铼金属有机化合物展现出不同的反应特性.研究结果表明,[MnRe(CO)6(μ-H){μ-CH3SC(S)IMes2}]配合物具有催化质子还原成氢气的能力.The VIIB group organometallic compounds of Mn or Re have been widely investigated on the synthe- sis, characterization, possible reactivity properties and catalytic activities. Compared to the use of NHCs as ligands, the exploration in the field of carbene dithiocarboxylate（ NHC·CS2 ） coordination with metal is very lack. Herein reported the synthesis, characterization, reactivity and electrochemical studies of a series of Mn and Re organometallic complexes containing NHC · CS2 ligands, concluding three mononuclear complexes and three dinuclear complexes. Those compounds were characterized by elemental analysis, IR, 1H NMR and 13C NMR. Compared to R3P · CS2 ligands, Mn-Re dinuclear organometallie complexes containing NHC · CS2 ligands showed different reactivity. The electrochemical studies of [ MnRe（ CO）6（μ-n） {μ-CHzSC （S） · IMes2 / ] were explored, and the results showed it possesses the potential catalytic property for proton reduction of acetic acid to give hydrogen under electrochemical conditions, which may be considered as a model in the research of the active site of [ Fe-Fe ] hydrogenases.
