2-Amino-6-methyl-pyridinium 4-hy-droxy-benzoate

Abstract

In the title mol-ecular salt, C6H9N2 (+)·C7H5O3 (-), the dihedral angle between the benzene ring and the CO2 group in the anion is 6.1 (2)°. In the crystal, the cation and anion are linked by N-H⋯O and C-H⋯O hydrogen bonds, and the anions are connected by O-H⋯O hydrogen bonds, forming a three-dimensional network.
