The title Schiff base compound, C(19)H(16)N(2)O(3), prepared by the reaction of 2-meth-oxy-1-naphthyl-aldehyde and 2-hydroxy-benzohydrazide, crystallizes with two independent mol-ecules in the asymmetric unit. Each mol-ecule exists in a trans configuration with respect to the methyl-idene group. The naphthyl ring system make dihedral angles of 65.0 (2)° and 55.8 (2)° with the planes of the benzene rings. Intra-molecular N-H⋯O and O-H⋯O hydrogen bonds help to stabilize the mol-ecular conformations. In the crystal structure, mol-ecules are linked into one-dimensional chains parallel to the c axis by inter-molecular O-H⋯N and O-H⋯O hydrogen bonds.
席夫碱化合物C(19)H(16)N(2)O(3)由2-甲氧基-1-萘甲醛与2-羟基苯甲酰肼反应制得，其不对称单元中含有两个独立分子。每个分子相对于亚甲基呈反式构型。萘环系统与苯环平面的二面角分别为65.0 (2)°和55.8 (2)°。分子内的N-H⋯O和O-H⋯O氢键有助于稳定分子构象。在晶体结构中，分子通过分子间的O-H⋯N和O-H⋯O氢键连接成平行于c轴的一维链。
