In the title complex, [Mn(C(19)H(12)BrN(3)O(2))Cl(C(3)H(7)NO)], the Mn(III) ion is coordinated by two N and two O atoms from the tetra-dentate Schiff base ligand, one O atom from the dimethyl-formamide ligand and a Cl anion in a distorted octa-hedral geometry. In the crystal structure, weak inter-molecular C-H⋯Cl hydrogen bonds link the mol-ecules into centrosymmetric dimers with a short distance of 3.878 (3) Å between the centroids of the aromatic rings.
