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

Mentions: Fig. 1 ▸ shows a possible formation process for the 3,3-dimethyl-4-(propan-2-yl­idene)thietane-2,2-bis­(thiol­ate) ligand via rearrangement of the di­thione starting material and its reaction to form compound (I). Similar rearrangements of di­thio­nes have been reported previously (Elam & Davis, 1967 ▸). Herein, we report the synthesis conditions and crystal structure of the title complex (I).
