title: 2-Amino-3-nitro-benzoic acid.
abstract: The title compound, C(7)H(6)N(2)O(4), is approximately planar (r.m.s. deviation = 0.026 Å for the 13 non-H atoms). The mol-ecular structure is stabilized by intra-molecular N-H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol-ecules are linked via inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional network.
