In the title compound, [[Cu(C13H10BrN2O)Cl]n, the CuII atom has a slightly distorted square–pyramidal coordination. The Cu atom is coordinated in the basal plane by two N atoms and one O atom of the Schiff base ligand, and by a Cl atom. The Cl atom of a symmetry-related molecule bridges the Cu atoms, so forming a slightly distorted square-pyramidal configuration at the Cu atom.
