A novel hexairon cluster with one disulfide and two Ph2PCS3−ligands

The title compound, hexadecacarbonylbis{μ 3 -[(diphenylphosphanyl)methanediidyl]sulfanido}-μ 4 -disulfido(2−)-hexairon(4 Fe — Fe ), [Fe 6 (C 13 H 10 PS) 2 (S 2 )(CO) 16 ], contains two inversion-related [Fe 3 (Ph 2 PCS)(CO) 8 ] subclusters linked by an equatorial disulfide bond [S—S = 2.1490 (9) Å]. Each Ph 2 PCS 3− ligand is coordinated to a triiron core in a μ 3 -κ P :κ 2 C :κ 2 S fashion.
