Bis{μ-4,4′-dibromo-2,2′-[o-phenylenebis(nitrilomethylidyne)]diphenolato}bis[chloridomanganese(III)]N,N-dimethylformamide disolvate

Abstract

The asymmetric unit of the title compound, [Mn2(C20H12Br2N2O2)2Cl2]·2C3H7NO, contains one half of a centrosymmetric dinuclear MnIII complex and an N,N-dimethyl­formamide solvent mol­ecule. In the complex, the two MnIII ions are bridged by two O atoms from two symmetry-related N,N′-bis­(5-bromo­salicyl­idene)-1,2-diimino­benzene dianionic ligands with the longer Mn—O distance of 2.703 (3) Å, thus each Mn ion is six-coordinated by two N and three O atoms from the two dianionic ligands and one capping Cl atom in a distorted octa­hedral environment. The crystal structure displays inter­molecular π–π inter­actions between adjacent benzene rings, with a shortest centroid–centroid distance of 3.673 (2) Å, and inter­molecular C—H⋯O, C—H⋯ Cl and C—H⋯ Br hydrogen bonds.
