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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
