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

In the title mol­ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (−), the 2-amino-5-methyl­pyridinium cation is essentially planar, with a maximum deviation of 0.023 (1) Å. There is an intra­molecular O—H⋯O hydrogen bond in the 3,5-dinitro­salicylate anion, which generates an S(6) ring motif. In the...

Descripción
Sumario:In the title mol­ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (−), the 2-amino-5-methyl­pyridinium cation is essentially planar, with a maximum deviation of 0.023 (1) Å. There is an intra­molecular O—H⋯O hydrogen bond in the 3,5-dinitro­salicylate anion, which generates an S(6) ring motif. In the crystal, the protonated N atom and the 2-amino group are hydrogen bonded to the carboxyl­ate O atoms via a pair of N—H⋯O hydrogen bonds, forming an R (2) (2)(8) ring motif. Weak inter­molecular C—H⋯O inter­actions help to further stabilize the crystal structure.
