Abstract: The molecule of the title compound, [CuNa(C₁₈H₁₈N₂O₄)(ClO₄)(CH₃OH)], is almost planar with mean deviation of 5.2 (8)°. The coordination environment of the Cu^II ion is distorted square-planar and it is N₂O₂-chelated by the 6,6'-dimethoxy-2,2'-[ethane-1,2-diylbis(nitrilomethylidyne)]diphenolate Schiff base ligand. The Na atom is chelated by the four O atoms of the Schiff base ligand, and coordinated by a methanol molecule and a perchlorate anion. The six-coordinate Na atom adopts a distorted octahedral coordination geometry. The O atoms of the perchlorate anion are disordered over two sites with site-occupancy factors of 0.697 (5) and 0.303 (5). O-HO hydrogen bonding occurs.
