In the title compound, C13H9N5O7, one of the nitro groups is twisted away from the attached benzene ring by 16.21 (8)°.The dihedral Storage Cabinets angle between the two benzene rings is 4.
63 (1)°.The molecular structure is stabilized by intramolecular N—H.O and O—H.
N hydrogen bonds which generate an S(6) ring motif.The molecules pack as layers parallel to HERBATINT 10N the ab plane; molecules of adjacent layers are linked into chains along the [101] direction through N—H.O hydrogen bonds.
