In the title compound, C(17)H(14)O(6), the benzopyran ring system is essentially planar and forms a dihedral angle of 6.84 (4)° with the other benzene ring. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by O-H⋯O hydrogen bonds. The crystal packing is controlled by C-H⋯π and π-π stacking inter-actions involving the benzopyran and benzene rings, with centroid-centroid distances between 3.645 (2) and 3.986 (2) Å.
在标题化合物C₁₇H₁₄O₆中，苯并吡喃环系基本呈平面状，与另一个苯环形成6.84 (4)°的二面角。在晶体结构中，中心对称相关的分子通过O—H⋯O氢键连接成二聚体。晶体堆积由涉及苯并吡喃环和苯环的C—H⋯π和π - π堆积相互作用控制，质心间距在3.645 (2)至3.986 (2) Å之间。
