Abstract: The title compound, C7H8NO2+·NO3-·C7H7NO2, exists in the form of a protonated dimer of two anilinium-3-carboxylate molecules related by an inversion center, and a nitrate anion located on a twofold rotation axis. The bridging H atom occupies, with equal probability, the two sites associated with the carboxyl atoms. In addition to the strong O-H
O hydrogen bond, in the crystal, the various units are linked via N-H
O and C-H
O hydrogen bonds forming a three-dimensional structure.
