4-Methoxybenzamidinium acetate

Abstract

The title compound, C8H11N2O+·CH3CO2−, was synthesized by a reaction between 4-methoxybenzamidine (4-amidinoanisole) and acetic acid. In the cation, the amidinium group forms a dihedral angle of 11.65 (17)° with the mean plane of the benzene ring. The ionic components are associated in the crystal via N—H+...O− hydrogen bonds, resulting in a one-dimensional structure consisting of dimers and catemers and orientated approximately along the c axis.
