title: 4-Meth-oxy-benzamidinium 2,6-dimeth-oxy-benzoate.
abstract: The title compound, C(8)H(11)N(2)O(+)·C(9)H(9)O(4) (-), was synthesized by the reaction of 4-meth-oxy-benzamidine (4-amidino-anisole) and 2,6-dimeth-oxy-benzoic acid. The structure consists of non-planar pairs of hydrogen-bonded 4-meth-oxy-benzamidinium cations and 2,6-dimeth-oxy-benzoate anions. In the cation, the amidinium group is tilted by 27.94 (10)° with respect to the benzene ring. In the anion, the sterically bulky ortho-meth-oxy substituents force the carb-oxy-ate group to be twisted away from the plane of the benzene ring by 73.24 (6)°. The ions are further associated in the crystal into chains along the b-axis direction by inter-molecular N-H⋯O hydrogen bonds.
