title: Bis{μ-4,4'-dibromo-2,2'-[o-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato}bis-[chloridomanganese(III)] N,N-dimethyl-formamide disolvate.
abstract: The asymmetric unit of the title compound, [Mn(2)(C(20)H(12)Br(2)N(2)O(2))(2)Cl(2)]·2C(3)H(7)NO, contains one half of a centrosymmetric dinuclear Mn(III) complex and an N,N-dimethyl-formamide solvent mol-ecule. In the complex, the two Mn(III) ions are bridged by two O atoms from two symmetry-related N,N'-bis-(5-bromo-salicyl-idene)-1,2-diimino-benzene 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 octa-hedral environment. The crystal structure displays inter-molecular π-π inter-actions between adjacent benzene rings, with a shortest centroid-centroid distance of 3.673 (2) Å, and inter-molecular C-H⋯O, C-H⋯ Cl and C-H⋯ Br hydrogen bonds.
