The dinuclear title compound, [Fe(2)(C(2)H(4)S(2))(C(24)H(20)OP(2))(CO)(5)] or (μ-SCH(2)CH(2)S-μ)Fe(2)(CO)(5)[Ph(2)PP(O)Ph(2)], con-tains a butterfly-shaped Fe(2)S(2) core in which the Fe⋯Fe separation is 2.5275 (6) Å. One of the Fe atoms is also coordinated to three carbonyl ligands and the other to two carbonyl ligands and one phosphane ligand [Ph(2)PP(O)Ph(2)]. Both Fe-atom geometries could be described as grossly distorted octa-hedral and the Ph(2)PP(O)Ph(2) ligand lies trans to the Fe⋯Fe link.
