title: Bis[1,2-bis-(eth-oxy-carbon-yl)ethene-1,2-dithiol-ato-κ(2) S,S']bis-(η(5)-penta-methyl-cyclo-penta-dien-yl)tetra-μ3-sulfido-diiron(IV)diiron(III)(3 Fe-Fe).
abstract: The title compound, [Fe4(C10H15)2(C8H10O4S2)2S4], contains a twisted Fe4S4 cubane-like core. A twofold rotation axis passes through the Fe4S4 core, completing the coordination of the four Fe atoms with two penta-methyl-cyclo-penta-dienyl ligands and two chelating dithiol-ate ligands. There are three short Fe-Fe and three long Fe⋯Fe contacts in the Fe4S4 core, suggesting bonding and non-bonding inter-actions, respectively. The Fe-S bonds in the Fe4S4 core range from 2.1523 (5) to 2.2667 (6) Å and are somewhat longer than the Fe-S bonds involving the dithiol-ate ligand.
