Abstract

In this paper, a novel diiron ethane-1,2-dithiolate complex [Fe-2(CO)(4){kappa(2)-(Ph2P)(2)(1,2-C6H4)}(mu-SCH2CH2S)] has been prepared and structurally characterized. Treatment of the parent complex [Fe-2(CO)(6)(mu-SCH2CH2S)] with 1 equivalent of 1,2-bis(diphenylphosphino)benzene and Me3NO.2H(2)O as the oxidative agent gave the title complex in good yield. The title complex has been characterized by elemental analysis, IR, H-1 NMR, P-31{H-1} NMR, C-13{H-1} 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 H-2 in the presence of acetic acid.
