title: 2-[4-(4,5-Dihydro-1H-imidazol-2-yl)phen-yl]-4,5-dihydro-1H-imidazol-3-ium 4-amino-benzoate.
abstract: In the cation of the title compound, C(12)H(15)N(4) (+)·C(7)H(6)NO(2) (-), the benzene ring makes dihedral angles of 30.51 (9) and 25.64 (9)° with the imidazole and imidazolinium rings, respectively. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen-bonding inter-actions link the mol-ecules into a three-dimensional network.
