Abstract: In the title compound, [Cu(C₁₉H₁₈Br₂N₂O₂)], the Cu^II ion is in a tetrahedrally distorted planar geometry, involving two N and two O atoms from the tetradentate Schiff base ligand. Intermolecular C-HO hydrogen bonds form an eight-membered R₂²(8) motif. The dihedral angle betwen two benzene rings is 36.34 (9)°. There are intermolecular CuBr [3.4566 (5) Å] and Cu·N [3.569 (3) Å] contacts, which are significantly shorter than the sum of van der Waals radii of the relevant atoms. These interactions, along with the intermolecular C-H and - [centroid-centroid distances of 3.709 (1) and 3.968 (2) Å] interactions, link neighbouring molecules into a one-dimensional infinite chain along the c axis.
