Abstract: The asymmetric unit of the title compound, C₁₄H₁₈N₃O⁺·Cl^-·H₂O, comprises a substituted amido-naphthyridine cation, a chloride anion and a water molecule of crystallization. Intramolecular C-HO hydrogen bonds generate six-membered rings, producing an S(6) ring motif. The amido group is twisted from the naphthyridine ring, making a dihedral angle of 17.65 (7)°. The crystal structure is stabilized by intermolecular N-HO, N-HCl, O-HCl (× 2), and C-HO (× 2) hydrogen bonds. These interactions linked neighbouring molecules into chains along the a and b axes of the crystal, thus forming molecular sheets parallel to the (001) plane.
