Abstract

The new complexes Fe₂(S₂C_nH _2n)(CO)₂(dppv)₂ (n = 2, 3; dppv = cis-1,2-C₂H₂(PPh₂)₂) form adducts with AlBr₃ and B(C₆F₅)₃, which adopt the "rotated structure" proposed for the active site of the Fe-only hydrogenases - the propanedithiolate is significantly more Lewis basic due to nonbonded interactions between the dithiolate strap and the ligands on Fe.
