The mol-ecule of the title compound, C(13)H(10)N(2)O(4), is almost planar with a dihedral angle between the benzene rings of 1.99 (13)°. The nitro group and its parent benzene ring are oriented at a dihedral angle of 7.6 (3)°. Intra-molecular C-H⋯O and N-H⋯O hydrogen bonds form two planar S(6) motifs. Inter-molecular O-H⋯O=C hydrogen bonds join mol-ecules into chains extending along the c axis.
