      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.
