The title salt, C8H11N2O +·HSO4 -, has been synthesized by the reaction between 4-methoxybenzamidine and sulfuric acid. The asymmetric unit comprises a nonplanar 4-methoxybenzamidinium cation and one hydrogen sulfate anion. In the cation, the amidinium group has two identical C-N bonds [1.306(2) and 1.308(2)Å], and its plane forms a dihedral angle of 6.49(8)°with the mean plane of the benzene ring. The ionic components are associated in the crystal via N-H+⋯O-, resulting in chains running approximately along the b-axis direction whicg are interconnected by O-H⋯O- hydrogen bonds.

Abstract
The title salt, C8H11N2O +·HSO4 -, has been synthesized by the reaction between 4-methoxybenzamidine and sulfuric acid. The asymmetric unit comprises a nonplanar 4-methoxybenzamidinium cation and one hydrogen sulfate anion. In the cation, the amidinium group has two identical C-N bonds [1.306(2) and 1.308(2)Å], and its plane forms a dihedral angle of 6.49(8)°with the mean plane of the benzene ring. The ionic components are associated in the crystal via N-H+⋯O-, resulting in chains running approximately along the b-axis direction whicg are interconnected by O-H⋯O- hydrogen bonds.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
