Synthesis, structure, and third-order non-linear optical properties of Mo/S cluster [Fe(DMF)6][Mo2(μ2-S)2S4]

Hexa-kis-(dimethyl-formamide-κO)manganese(II) μ-oxido-bis-[trichlorido-ferrate(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].
