Abstract: The title compound, [Fe₄(SEt)₂(S₂)(CO)₁₂], contains two inversion-related [Fe₂(SEt)(CO)₆] subclusters linked by a disulfide bond [S-S 2.1294 (14) Å]. In each subcluster, each Fe^II atom is coordinated by three terminal carbonyl C atoms [Fe-C 1.792 (3)-1.814 (4) Å], two bridging S atoms [Fe-S 2.2496 (9)-2.2606 (8) Å] and the other Fe atom [Fe-Fe = 2.5311 (7) Å], and exhibits a distorted octahedral geometry, with trans angles ranging from 155.56 (12) to 160.14 (15)°.
