Imidazolium 3-nitrobenzoate

Abstract

In the title compound, C3H5N2+·C7H4NO4−, the benzene ring forms a dihedral angle of 40.60 (5)° with the imidizolium ring. The nitrobenzoate anion is approximately planar: the benzene ring makes dihedral angles of 3.8 (3) and 3.2 (1)° with the nitro and carboxylate groups, respectively. In the crystal structure, the cations and anions are linked by intermolecular N—H...O hydrogen bonds, forming a zigzag chain along the b axis.
