In the title compound, [Cu(C21H22N2O2)], the cyclohexyl ring
adopts a chair conformation with the two imine groups linked
at equatorial positions. The CuII ion is coordinated by two N
atoms and two O atoms from the bis-Schiff base ligand in a
slightly distorted square-planar geometry. The dihedral angle
between the two benzene rings is 45.89 (9). The crystal
structure is devoid of any classical hydrogen bonds. However,
intermolecular C—H O interactions are present and
stabilize the structure.

bis-Schiff bases, see: Lashanizadegan & Boghaei (2002); Rabie
et al. (2008).
