【 摘 要 】

In the title hydrated mol­ecular salt, C7H11N2+·C7H6NO2−·2H2O, the cation is protonated at the pyridine N atom and the dihedral angle between the benzene ring and the CO2− group in the anion is 8.5 (2)°. In the crystal, the cation forms an N—H⋯O hydrogen bond to the anion and the anion forms two N—H⋯O hydrogen bonds to adjacent water mol­ecules. Both water mol­ecules form two O—H⋯O hydrogen bonds to carboxyl­ate O atoms. In combination, these hydrogen bonds generate a three-dimensional network and two weak C—H⋯π inter­actions are also observed.
