In the title compound, [Cu(C16H8Br3N2O)2]·C2H6OS, the CuII atom is tetra-coordinated in a square-planar coordination, being surrounded by two N atoms and two O atoms from two N,O-bidentate (E)-1-[(2,4,6-tri-bromo-phen-yl)diazen-yl]naphthalen-2-olate ligands. The two N atoms and two O atoms around the metal center are trans to each other, with an O-Cu-O bond angle of 177.90 (16)° and a N-Cu-N bond angle of 177.8 (2)°. The average distances between the CuII atom and the coordinated O and N atoms are 1.892 (4) and 1.976 (4) Å, respectively. In the crystal, complexes are linked by C-H⋯O hydrogen bonds and by π-π inter-actions involving adjacent naphthalene ring systems [centroid-centroid distance = 3.679 (4) Å]. The disordered DMSO mol-ecules inter-act weakly with the complex mol-ecules, being positioned in the voids left by the packing arrangement of the square-planar complexes. The DMSO solvent mol-ecule is disordered over two positions with occupancies of 0.70 and 0.30.
