Abstract: In the title compound, C13H10N2O4, the nitro N atom deviates by 0.031 (2) Å from the plane of the benzene ring to which it is attached. The aromatic rings are oriented at a dihedral angle of 50.6 (1)°. An intramolecular N-H...O hydrogen bond occurs. In the crystal, inversion dimers are formed by pairs of O-H...O interactions.
