Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.007 Å; R factor = 0.057; wR factor = 0.102; data-to-parameter ratio = 11.9. In the title complex, [Cu(C 28 H 18 N 2 O 2 )], the Cu II atom is coordinated by two N [Cu-N = 1.913 (4) and 1.919 (4) Å ] and two O [Cu-O = 1.872 (3) and 1.880 (3) Å ] atoms from the o-phenylenebis(naphthalideneamine) ligand in a distorted square-planar geometry.
