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-HN hydrogen bonds between the methanol molecule and the Schiff base anion stabilize the structural set-up.

Organic ligands based on oxadiazole or carboxylate groups have both good coordination ability and diverse coordination modes, see: Hu et al. (2008).
