Abstract: In the title molecular salt, C₁₂H₂₂N₅⁺·Cl^-, the cation is protonated at the dimethyl-substituted tertiary N atom. The piperidine ring adopts a chair conformation with the exocyclic N-C bond in an equatorial orientation. The dihedral angle between the piperidine ring (all atoms) and the pyrimidine ring is 14.00 (1)°. In the crystal, the ions are connected by N-HN hydrogen bonds, forming inversion dimers, which are further connected by N-HCl hydrogen bonds. Aromatic [pi] - [pi] stacking interactions [centroid-centroid separation = 3.4790 (9) Å] are also observed in the structure.
