Guanidinium 3-nitrobenzoate

Abstract

The title compound, CH6N3+·C7H4NO4−, an anhydrous guanidinium salt, shows a N—H...O hydrogen-bond network in which the guanidinium cation is involved in three cyclic R21(6) hydrogen-bonding associations with separate carboxylate O-atom acceptors. Further peripheral associations include a cyclic R12(4) cation–anion interaction, forming interlinked undulating sheets in the three-dimensional structure.
