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

In the anion of the title mol­ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (−), 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....

Sumario:In the anion of the title mol­ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (−), 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.
