摘      要：In this paper,a novel diiron ethane-1,2-dithiolate complex[Fe2(CO)4{κ2-(Ph2P)2(1,2-C6H4)}(μ-SCH2CH2S)]has been prepared and structurally characterized.Treatment of the parent complex[Fe2(CO)6(μ-SCH2CH2S)]with 1 equivalent of 1,2-bis(diphenylphosphino)benzene and Me3NO?2H2O as the oxidative agent gave the title complex in good yield.The title complex has been characterized by elemental analysis,IR,1H NMR,31P{1H}NMR,13C{1H}NMR spectroscopy,and X-ray crystallography.X-ray crystal structure of the title complex contains a butterfly diiron cluster with a bridging ethane-1,2-dithiolate,four terminal carbonyls,and a chelating 1,2-bis(diphenylphosphino)benzene.In addition,electrochemical studies revealed that the title complex can catalyze the reduction of protons to H2 in the presence of acetic acid.
