A novel hexa­iron cluster with one disulfide and two Ph₂PCS^3- ligands

The title compound, hexa­deca­carbonyl­bis­{[mu]₃-[(diphenylphos­phanyl)methanediidyl]sulfanido}-[mu]₄-di­sulfido­(2-)-hexa­iron(4 Fe-Fe), [Fe₆(C₁₃H₁₀PS)₂(S₂)(CO)₁₆], contains two inversion-related [Fe₃(Ph₂PCS)(CO)₈] subclusters linked by an equatorial di­sulfide bond [S-S = 2.1490 (9) Å]. Each Ph₂PCS^3- ligand is coordinated to a triiron core in a [mu]₃-[kappa]P:[kappa]²C:[kappa]²S fashion.
