2-Amino-5-nitrobenzoic acid
Özet
In the title compound, C7H6N2O4, an intramolecular N-H center dot center dot center dot O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H center dot center dot center dot O hydrogen bonds generate R-2(2)(8) loops. Intermolecular N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds then link the dimers, generating R-3(3)(16) R-2(1)(6) motifs. The whole molecule is essentially planar, with the greatest deviation from the mean plane being 0.065 (2) angstrom.
