Bis{1-[(E)-(2-chloro-phen-yl)diazen-yl]naphthalen-2-olato}copper(II)

The Cu(II) atom in the title compound, [Cu(C16H10ClN2O)2], is located on an inversion center and is tetra-coordinated by two N and two O atoms from two bidentate 1-[(E)-(2-chloro-phen-yl)diazen-yl]naphthalen-2-olate ligands, forming a square-planar complex. In the crystal, mol-ecules are linked via weak C-H⋯O and C-H⋯Cl hydrogen bonds, forming chains propagating along [010]. There are also π-π inter-actions present involving adjacent naphthalene rings [centroid-centroid distance = 3.661 (13) Å].
