In the title compound, C(10)H(14)N(3) (+)·Cl(-), the tetra-hydro-pyridinium 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).
