Bis{1-[(E)-o-tolyl-diazen-yl]-2-naphtho-l-ato}copper(II).

In the title complex, [Cu(C(17)H(13)N(2)O)(2)], the Cu(II) atom is tetra-coordinated by two N atoms and two O atoms from two bidentate 1-[(E)-o-tolyl-diazen-yl]-2-naphtho-late ligands, forming a slightly distorted square-planar environment. The two N atoms and two O atoms around the Cu(II) atom are trans to each other, with an O-Cu-O bond angle of 177.00 (9)° and an N-Cu-N bond angle of 165.63 (10)°. The average distances between the Cu(II) atom and the coordinated O and N atoms are 1.905 (2) and 1.995 (2)Å, respectively.
