title: {2,2'-[Cyclo-hexane-1,2-diylbis(nitrilo-methanyl-ylidene)]diphenolato}copper(II).
abstract: The title compound, [Cu(C(20)H(20)N(2)O(2))], crystallizes with two independent mol-ecules in the asymmetric unit. In each mol-ecule, the Cu(II) atom occupies the tetra-dentate N(2)O(2) cavity of the salen-type Schiff base ligand, adopting a distorted square-planar geometry with r.m.s. deviations of the coordin-ating atoms of 0.0522 (2) and 0.1128 (4) Å. No hydrogen bonds or π-π stacking inter-action are observed.
