Abstract
In the title compound, [Cu(C19H16Br4N2O2)], the CuII ion and the substituted C atom of the diamine fragment lie on a crystallographic twofold rotation axis. The geometry around the CuII ion is distorted square-planar, which is defined by the N2O2 donor atoms of the coordinated Schiff base ligand. The dihedral angle between the symmetry-related substituted benzene rings is 25.33 (14)°. The crystal structure is stabilized by an intermolecular π–π interaction [centroid–centroid distance = 3.8891 (18) Å].
