In the title salt, C3H5N2+ center dot C7H6NO2-, the carboxylate group of the 4-aminobenzoate anion forms a dihedral angle of 13.23 (17)degrees with respect to the benzene ring. There are N-H center dot center dot center dot O hydrogen-bonding interactions between the anion and cation, and weak intermolecular C-H center dot center dot center dot O contacts with carboxylate O-atom acceptors of the 4-aminobenzoate anion result in extended three-dimensional R-4(4)(22) and R-5(6)(30) edge-fused rings along the [100], [010] and [001] directions.
