4-Meth­oxy­benzamidinium hydrogen sulfate

The title salt, C(8)H(11)N(2)O(+)·HSO(4) (−), 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 bond...

Sumario:The title salt, C(8)H(11)N(2)O(+)·HSO(4) (−), 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.
