In the title compound, [Na4(C15H9N4O4)4(CH3OH)4], the N3O3 environment around the Na+ ion is distorted octa­hedral. In the unit cell, four Na+ ions are bridged by four Schiff base anions, leading to a tetra­nuclear complex with -4 symmetry. O—H⋯N hydrogen bonds between the methanol mol­ecule and the Schiff base anion stabilize the structural set-up.
