Abstract: The asymmetric unit of the title compound, C5H7N2+·C7H4NO4-·C7H5NO4, consists of an aminopyridinium cation, a 4-nitrobenzoate anion and a neutral 4-nitrobenzoic acid molecule. The pyridine ring forms dihedral angles of 64.70 (5)° and 70.37 (5)°, respectively, with the benzene rings of 4-nitrobenzoic acid and 4-nitrobenzoate. In the crystal structure, the cations, anions and the neutral 4-nitrobenzoic acid molecules are linked by O-H
O and N-HO hydrogen bonds, forming a two-dimensional network parallel to (001). Adjacent networks are cross-linked via C-HO hydrogen bonds and ![[pi]](/logos/entities/pi_rmgif.gif)
- stacking interactions [centroid-centroid distances 3.6339 (6) and 3.6566 (6) Å].
