In the title compound, C(15)H(13)NO(4), the dihedral angle between the substituted benzene rings is 9.9 (8)°. Part of the mol-ecule (the salicylaldimine segment) is disordered over two sets of sites, with a refined site-occupancy ratio of 0.550 (14):0.450 (14). Intra-molecular O-H⋯N hydrogen bonds form S(6) ring motifs. In the crystal, pairs of O-H⋯O hydrogen bonds link mol-ecules into centrosymmetric dimers with R(2) (2)(8) ring motifs. The crystal packing also features C-H⋯π inter-actions.
在标题化合物C₁₅H₁₃NO₄中，取代苯环之间的二面角为9.9 (8)°。分子的一部分（水杨醛亚胺片段）在两组位置上无序，精制的位点占有率比为0.550 (14):0.450 (14)。分子内O—H⋯N氢键形成S(6)环基序。在晶体中，O—H⋯O氢键对将分子连接成具有R₂²(8)环基序的中心对称二聚体。晶体堆积还具有C—H⋯π相互作用。
