In the title heterodinuclear complex, [CuNa(C8H7O3)2(ClO4)(CH3OH)]n, the CuII ion is five-coordinated by four O atoms from two 2-formyl-6-meth­oxy­phenolate anions and one O atom from a perchlorate anion in a distorted square-pyramidal geometry. The Na+ ion is six-coordinated by four O atoms from two 2-formyl-6-meth­oxy­phenolate ligands, one O atom of a methanol mol­ecule and one O atom of a perchlorate anion. The perchlorate anions link the Na+ and CuII ions, forming a chain along [010]. O—H⋯O hydrogen bonds connect the chains. π–π inter­actions are present between the benzene rings [centroid–centroid distances = 3.566 (2) and 3.702 (2) Å]. The O atoms of the perchlorate anion are disordered over two sets of sites, with an occupancy ratio of 0.481 (8):0.519 (8).
