Bis[1,2-bis­(eth­oxy­carbon­yl)ethene-1,2-dithiol­ato-κ²S,S′]bis­(η⁵-penta­methyl­cyclo­penta­dien­yl)tetra-μ₃-sulfido-diiron(IV)diiron(III)(3 Fe—Fe)

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 penta­methyl­cyclo­penta­dienyl ligands and two chelating dithiol­ate ligands. There are three short Fe—Fe and three long Fe...Fe contacts in the Fe₄S₄ core, suggesting bonding and non-bonding inter­actions, 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 dithiol­ate ligand.
