摘要：
Next to the monoclinic polymorph [Cheng et al. (2005). Acta Cryst. E61, m892-m894], the triclinic title compound, [Fe-4(C2H5S)(2)(S-2)(CO)(12)], is the second known form of this composition. The structure is composed of an [Fe-2(C2H5S)(S)(CO)(6)] subcluster, which is linked to its counterpart by an inversion centre located at the mid-point of the central disulfide bond. The Fe2S2 core of each subcluster exhibits a butterfly-like shape, with two S atoms bridging two Fe atoms. In the subcluster, each Fe atom is coordinated in a distorted octahedral coordination by three terminal carbonyl C atoms, two S atoms and one Fe atom. The crystal packing is accomplished through van der Waals interactions.
