Hexa­kis­(dimethyl­formamide-κO)manganese(II) μ-oxido-bis­[trichlorido­ferrate(III)]

The title compound, [Mn(C3H7NO)6][Fe2Cl6O], was obtained unintentionally as a product of an attempted synthesis of heterometallic complexes with Schiff base ligands using manganese powder and FeCl3·6H2O as starting materials. In the [Fe2OCl6]2− anion, the O atom and the Fe atom occupy positions with site symmetry and 3, respectively, resulting in a linear Fe—O—Fe angle and a staggered conformation. The octa­hedrally surrounded cation (site symmetry ) and the [Fe2Cl6O]2− anion are alternately stacked along [001]
