Abstract: In the title hydrated molecular salt, C₆H₇ClN⁺·C₂HO₄^-·0.5H₂O, the water O atom lies on a crystallographic twofold axis. In the crystal, the anions are linked by O-HO hydrogen bonds, forming chains propagating along the b axis. These chains are interconnected through O-HO hydrogen bonds from the water molecules and N-HO hydrogen bonds from the cations, building layers parallel to the ab plane.
