The title Schiff base compound, C(18)H(13)NO(2), is a zwitterion, with the naphthol hy-droxy group deprotonated and the imine N atom protonated. It adopts an E configuration about the central C=N double bond. The dihedral angle between the naphthyl ring system and the benzene ring is 1.73 (11)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, adjacent mol-ecules are connected by inter-molecular C-H⋯O hydrogen bonds, forming a supra-molecular ribbon along the b axis.
标题席夫碱化合物C(18)H(13)NO(2)是一种两性离子，萘酚羟基去质子化，亚胺N原子质子化。它围绕中心C=N双键采取E构型。萘基环系统与苯环之间的二面角为1.73 (11)°。分子内N-H⋯O氢键产生一个S(6)环 motif。在晶体中，相邻分子通过分子间C-H⋯O氢键相连，沿b轴形成一条超分子带。
