The title complex, [Fe2(C8H12S3)(CO)6] or [{Fe(CO)3}2 (μ-L)] [L = 3,3-dimethyl-4-(propan-2-ylidene)thietane-2,2-bis(thiolato)], consists of two Fe(CO)3 moieties double-bridged by a dithiolate ligand. Each of the two FeI atoms has a distorted anti-prismatic coordination environment consisting of three carbonyl groups, two S atoms of the dithiolate ligand and the neighboring FeI atom [Fe - Fe = 2.4921 (4) Å]. Weak C - H⋯O intermolecular interactions result in the formation of dimers. This is the second crystal structure reported with the 3,3-dimethyl-4-(propan-2-ylidene)thietane-2,2-bis(thiolate) ligand and the first in which it bridges two metal atoms.
