4-(o-Tol-yl)piperazin-1-ium chloride.

In the title mol-ecular salt, C(11)H(17)N(2) (+)·Cl(-), the piperazin-1-ium ring adopts a chair conformation with the aromatic ring in a pseudo-equatorial orientation. The dihedral angle between the benzene ring and the mean plane of the piperazin-1-ium ring is 51.22†(6)°. In the crystal, N-H⋯Cl hydrogen bonds link the mol-ecules into chains propagating in [100]. Weak C-H⋯π inter-actions also ocur.
