title: 2-Methyl-3,5-dinitro-benzoic acid.
abstract: In the title compound, C(8)H(6)N(2)O(6), the O atoms of the nitro groups, the methyl H atoms and the carboxyl C=O and C-OH groups are disordered over two sets of sites with an occupancy ratio of 0.595 (16):0.405 (16). In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds arise for both carboxyl disorder components and C-H⋯O bonds and weak C-H⋯π inter-actions consolidate the packing.
