Abstract

The title organic salt, C8H8N3 +·Cl−·H2O, exhibits a rich hydrogen-bonding network involving all constituent species. The water mol­ecules are engaged in strong O—H⋯Cl inter­actions with the chloride anions, two neighboring protonated 2-(1H-pyrazol-3-yl)pyridinium species inter­act via N—H⋯N bonds with two pyrazole rings. Further, a short and highly directional C—H⋯O inter­action is observed connecting the pyridinium ring to the water mol­ecule of crystallization. Weak C—H⋯Cl and N—H⋯Cl inter­actions contribute to the stabilization of the crystal structure.
