Abstract:
The title compound, [Fe(2)(C(3)H(6)S(2))(C(18)H(15)P)(2)(CO)(4)], which might serve as an active-site model of [FeFe]-hydrogenase, contains two fused Fe/S/C/C/C/S six-membered rings, one of which has a chair conformation and the other a boat conformation. Each Fe atom is coordinated by two carbonyl ligands, a triphenyl-phosphane ligand and a bis-bidentate dithiol-ate ligand, and also forms an Fe-Fe bond [2.5167 (16) Å]. Together, the six bonded atoms form a very distorted octa-hedral arrangement.
