Synthesis,Characterization and Molecular Structure of a Diiron Complex(μ-SCH2CH2CH2S-μ)Fe2(CO)5(Ph2PCH3)

The title complex,(μ-pdt)Fe(CO)(PhPCH)(pdt = SCHCHCHS),was obtained by the reaction of the parent complex(μ-pdt)Fe(CO)with PhPCHand MeNO·2HO in good yield(90%). The title complex was characterized by IR,~1H NMR,P{~1H} NMR andC{~1H} NMR spectroscopy as well as by single-crystal X-ray diffraction analysis. The molecular structure shows that the title complex contains a butterfly diiron propanedithiolate cluster with five terminal carbonyls and a monophosphine ligand PhPCH. The crystal packing diagram reveals that intermolecular C H···O hydrogen bonds between CHand carbonyls,π-π stacking interactions and van der Waals’ interactions stabilize the solid state to form a three-dimensional network.
