4-Methylbenzylammonium chloride hemihydrate

In the title hydrated salt, C8H12N+·Cl−·0.5H2O, the water O atom lies on a crystallographic twofold axis. In the crystal, the cation, anion and water molecule are linked to one another via C—H...Cl, O—H...Cl, N—H...O and N—H...Cl hydrogen bonds. The crystal structure is further stabilized by two weak C—H...π interactions involving the benzene ring to form a three-dimensional network.
