Abstract: The title compound, [Fe2(C7H6S3)(CO)6], was prepared as a biomimic for the active site of [FeFe]-hydrogenases. The central Fe2S2 core is in a butterfly conformation and each FeI atom has a pseudo-square-pyramidal coordination by three O atoms and two S atoms. The Fe-Fe distance is 2.471 (2) Å and the dihedral angle between the two Fe-S-Fe planes is 78.96 (7)°. The least-squares plane through the -S(C7H6S)S- bridge nearly bis­ects the mol­ecular structure: except for the two Fe(CO)3 units, all atoms are in this plane with an average deviation from the plane of 0.028 (3) Å. In the crystal, the mol­ecules are linked into chains along [001] by C-H...[pi](arene) inter­actions.
