2-Amino-5-methyl-pyridinium 4-methyl-benzoate.

ABSTRACT: The 4-methyl-benzoate anion of the title salt, C6H9N2(+)·C8H7O2(-), is nearly planar, with a dihedral angle of 6.26?(10)° between the benzene ring and the carboxyl-ate group. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H?O hydrogen bonds with an R2(2)(8) ring motif, forming an approximately planar ion pair with a dihedral angle of 9.63?(4)° between the pyridinium and benzene rings. The ion pairs are further connected via N-H?O and weak C-H?O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.
