title: Penta-carbonyl-1κC,2κC-(ferrocenyl-diphenyl-phosphine-1κP)[μ-2-(4-methyl-phen-yl)-2-aza-propane-1,3-dithiol-ato-1:2κS,S':S,S']diiron(I)(Fe-Fe).
abstract: The title compound, [Fe(2)(C(9)H(11)NS(2)){Fe(C(5)H(5))(C(17)H(14)P)}(CO)(5)], was prepared as an aza-dithiol-ato-iron model for the iron-only hydrogenase active site. The Fe(2)S(2) unit exhibits a butterfly conformation and the ferrocenyldiphenyl-phosphine ligand is trans to the Fe-Fe bond. The Fe-Fe distance of 2.5160 (8) Å is longer than found in related model structures. Intra-molecular C-H⋯S and inter-molecular C-H⋯O hydrogen bonds are observed.
