Penta­carbonyl-1κ2 C,2κ3 C-(ferrocenyl­diphenyl­phosphine-1κP)[μ-2-(4-methyl­phen­yl)-2-aza­propane-1,3-dithiol­ato-1:2κ4 S,S′:S,S′]diiron(I)(Fe—Fe)

摘要

The title compound, [Fe2(C9H11NS2){Fe(C5H5)(C17H14P)}(CO)5], was prepared as an aza­dithiol­ato–iron model for the iron-only hydrogenase active site. The Fe2S2 unit exhibits a butterfly conformation and the ferrocenyldiphenyl­phosphine 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. Intra­molecular C—H⋯S and inter­molecular C—H⋯O hydrogen bonds are observed.
