| Summary: | The title salt, C8H11N2O+·NO3−, was synthesized by a reaction between 4-methoxybenzamidine (4-amidinoanisole) and nitric acid. The asymmetric unit comprises a non-planar 4-methoxybenzamidinium cation and a nitrate anion. In the cation, the amidinium group has two similar C—N bond lengths [1.302 (3) and 1.313 (3) Å] and its plane forms a dihedral angle of 32.66 (5)° with the mean plane of the benzene ring. The nitrate–amidinium ion pair is not planar, as the dihedral angle between the planes defined by the CN2+ and NO3− units is 19.28 (6)°. The ionic components are associated in the crystal via N—H...O hydrogen bonds, resulting in a three-dimensional network.
