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, 1 H NMR and 13 C NMR. Compared to R3 P·CS2 ligands, Mn-Re dinuclear organometallic complexes containing NHC·CS2 ligands showed different reactivity. The electrochemical studies of [ MnRe ( CO ) 6 (μ-H ){μ-CH3 SC ( 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.
