In the title compound, C(19)H(16)O(3), an intra-molecular O-H⋯O=C hydrogen bond is formed between the hy-droxy and carbonyl groups on the naphthalene ring system, resulting in an S(6) ring. The angles between the C=O bond vector and the least-squares planes of the naphthalene ring system and the benzene ring are 27.63 (6) and 47.99 (7)°, respectively. The dihedral angle between the latter planes is 61.39 (5)°. In the crystal, two mol-ecules are connected by pairs of inter-molecular O-H⋯O=C hydrogen bonds, forming centrosymmetric dimers with an R(2) (2)(4) graph-set motif. The mol-ecular packing features C-H⋯π interactions.
在标题化合物C₁₉H₁₆O₃中，萘环体系上的羟基和羰基之间形成了分子内O-H⋯O=C氢键，形成了一个S(6)环。C=O键向量与萘环体系和苯环的最小二乘平面之间的夹角分别为27.63 (6)°和47.99 (7)°。后两个平面之间的二面角为61.39 (5)°。在晶体中，两个分子通过分子间O-H⋯O=C氢键对相连，形成具有R(2) (2)(4) 图形集 motif的中心对称二聚体。分子堆积具有C-H⋯π相互作用。
