In the title compound, C22H16N2O6, the naphthalene ring systems form a dihedral angle of 65.2 (1)°. Two O atoms of one of the nitro groups are disordered over two sets of sites with occupancy factors of 0.586 (15) and 0.414 (15). Weak C-HO intermolecular interactions are present, forming a ladder like structure along the a axis.
