The asymmetric unit of the title compound, C(14)H(18)N(3)O(+)·Cl(-)·H(2)O, comprises a substituted amido-naphthyridine cation, a chloride anion and a water mol-ecule of crystallization. Intra-molecular C-H⋯O 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 inter-molecular N-H⋯O, N-H⋯Cl, O-H⋯Cl (× 2), and C-H⋯O (× 2) hydrogen bonds. These inter-actions linked neighbouring mol-ecules into chains along the a and b axes of the crystal, thus forming mol-ecular sheets parallel to the (001) plane.
标题化合物C(14)H(18)N(3)O(+)·Cl(-)·H(2)O的不对称单元包含一个取代的酰胺基萘啶阳离子、一个氯离子和一个结晶水分子。分子内C-H⋯O氢键形成六元环，产生S(6)环 motif。酰胺基与萘啶环扭转，二面角为17.65 (7)°。晶体结构通过分子间N-H⋯O、N-H⋯Cl、O-H⋯Cl（×2）和C-H⋯O（×2）氢键得以稳定。这些相互作用将相邻分子沿晶体的a轴和b轴连接成链，从而形成平行于(001)平面的分子片层。
