In the centrosymmetric mononuclear title complex, [Cu(C₁₈H₂₀N₂O₂)₂], the Cu(II) atom is four-coordinated in a trans-CuN₂O₂ square-planar geometry with the N-Cu-O chelate angle being 89.97 (11)°. The dihedral angles made by the planes defined by the aromatic ring carbons of the 4-methyl-benzene and 2,4-dimethyl-benzene fragments with the plane defined by the chelate ring are 13.43 (15) and 82.69 (13)° respectively. The angle between the planes defined by the aromatic carbons of the two rings is 89.40 (16)°. A a weak intra-molecular C-H⋯N hydrogen bond occurs.
