2-(4-Aminophenyl)-3,4,5,6-tetrahydropyrimidin-1-ium chloride

Abstract

In the title compound, C10H14N3+·Cl−, the tetrahydropyridinium ring of the cation, which adopts a slightly distorted envelope conformation, is disordered over two orientations with an occupancy ratio of 0.653 (5):0.347 (5). The amidinium fragment of the major conformer is twisted relative to the benzene ring by 22.5 (6)° and the two C—N bond lengths of this fragment are similar [1.3228 (16) and 1.319 (2) Å]. In the crystal, the chloride anions are involved in three N—H...Cl hydrogen bonds, which link the components into a two-dimensional hydrogen-bonded network parallel to (010).
