The title compound, [Cu(C₁₃H₁₆NO₂)₂], is a mononuclear copper(II) complex derived from the Schiff base ligand 2-(cyclopentyliminomethyl)-5-methoxyphenol and copper acetate. The Cu^II atom is four-coordinated by the phenolate O atoms and imine N atoms from two Schiff base ligands, in a highly distorted square-planar geometry. The O- and N-donor atoms are mutually trans and the dihedral angle between the two benzene rings is 55.8 (3)°.
