Abstract
In the structure of the title salt, C6H9N2 +·C7H6NO2 −, the 4-aminobenzoate anions are linked to adjacent anions and 2-amino-4-methylpyridinium cations via N—H⋯O hydrogen bonds, forming a three-dimensional supramolecular structure. The crystal structure also shows a weak C—H⋯O hydrogen bond between adjacent anions. Within the 4-aminobenzoate anion, the carboxylate group is twisted by 14.0 (4)° with respect to the benzene ring.
