μ-Oxido-bis({4,4′-dibromo-2,2′-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolato}manganese(III))

Abstract

The title compound, [Mn2(C16H12Br2N2O2)2O], is an unusual dinuclear manganese(III) complex. Each MnIII ion has a distorted square-pyramidal coordination geometry. In the basal plane, the Mn atom is coordinated by two N atoms and two O atoms of the Schiff base ligand. The apical position is occupied by a bridging O2− ion, which links to the other MnIII ion in the complex; this bridging O atom lies on a twofold rotation axis.
