ABSTRACT: In the title compound, [Cu(C(19)H(16)Br(4)N(2)O(2))], the Cu(II) ion and the substituted C atom of the diamine fragment lie on a crystallographic twofold rotation axis. The geometry around the Cu(II) ion is distorted square-planar, which is defined by the N(2)O(2) 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 inter-molecular ?-? inter-action [centroid-centroid distance = 3.8891?(18)?Å].
