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 FeII 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)°.
