2-Methyl-3,5-dinitrobenzoic acid

In the title compound, C8H6N2O6, 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...

Description
Summary:In the title compound, C8H6N2O6, 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 interactions consolidate the packing.
