In molecules of the title compound, C14H12N2O4, the conformation is dominated by an intramolecular N-H...O hydrogen bond in which one of the nitro O atoms is the acceptor. The molecules are linked by paired C-H...O hydrogen bonds [H...O = 2.41 Angstrom, C...O = 3.2990 (17) Angstrom and C-H...O = 156degrees] into centrosymmetric R-2(2)(14) dimers; these dimers are linked weakly into chains of alternating R-2(2)(14) and R-4(4)(40) rings by a second C-H...O hydrogen bond [H...O = 2.55 Angstrom, C...O = 3.5006 (15) Angstrom and C-H...O = 162degrees].
