2-Amino-4-methyl-pyridinium 4-amino-benzoate

Abstract

In the structure of the title salt, C6H9N2 +·C7H6NO2 -, the 4-amino-benzoate anions are linked to adjacent anions and 2-amino-4-methyl-pyridinium cations via N - H⋯O hydrogen bonds, forming a three-dimensional supra-molecular structure. The crystal structure also shows a weak C - H⋯O hydrogen bond between adjacent anions. Within the 4-amino-benzoate anion, the carboxyl-ate group is twisted by 14.0 (4)° with respect to the benz-ene ring.
