In the title heterodinuclear complex, [CuNa(C8H7O3)2(NO3)]n, the CuII ion is five-coordinated in a square-pyramidal arrangement by four atoms of two different ligand molecules in equatorial positions and one remote nitrate O atom in the apical position. The Na+ ion is eight-coordinated by four ligand O atoms and four nitrate O atoms. The ligand links the CuII and Na ions, forming a layered arrangement extending parallel to (001)
