Abstract [en]

The title compound, [Fe-2(C5H11NS2)(C12H11P)(CO)(5)], has been prepared and characterized as a model compound of the iron hydrogenase active site through controlled CO ligand displacement of (mu-SCH2)(2)N(CH2CH2CH3)[Fe-2(CO)(6)] with diphenylphosphine. The central Fe2S2 structure is in a butterfly conformation, and each Fe atom displays pseudo-square-pyramidal geometry. The phosphine group occupies an apical position. The propyl group on the bridging N atom is in an equatorial position and takes a zigzag form. In the crystal packing, adjacent pairs of molecules are associated by S center dot center dot center dot S (3.625 angstrom) intermolecular nonbonded weak interactions.
