2-Amino-4-methylpyridinium 2-hydroxy-3,5-dinitrobenzoate

In the anion of the title molecular salt, C6H9N2 +·C7H3N2O7 −, the two nitro groups are twisted from the attached benzene ring with dihedral angles of 27.36 (10) and 4.86 (11)°. The anion is stabilized by an intramolecular O—H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N—H⋯O and C—H⋯O interactions and are further consolidated by C—H⋯π interactions, to generate a three-dimensional network. A short O⋯N contact of 2.876 (2) Å also occurs.
