title: Imidazolium 4-amino-benzoate.
abstract: In the title salt, C(3)H(5)N(2) (+)·C(7)H(6)NO(2) (-), the carboxyl-ate group of the 4-amino-benzoate anion forms a dihedral angle of 13.23 (17)° with respect to the benzene ring. There are N-H⋯O hydrogen-bonding inter-actions between the anion and cation, and weak inter-molecular C-H⋯O contacts with carboxyl-ate O-atom acceptors of the 4-amino-benzoate 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.
