In the title moleclue, C16H14O4, the dihedral angle between the benzene rings is 16.1 (3)°. The meth-oxy group is essentially coplanar with the benzene ring to which it is attached, with a C-O-C C torsion angle of 5.5 (9)°. In the crystal, mol-ecules are linked by O-H⋯O and bifurcated O-H⋯(O,O) hydrogen bonds, forming a three-dimensional network. The structure was refined as a two-component inversion twin.
在标题分子C₁₆H₁₄O₄中,苯环之间的二面角为16.1 (3)°。甲氧基与其所连接的苯环基本共面,C—O—C—C扭转角为5.5 (9)°。在晶体中,分子通过O—H⋯O和分叉的O—H⋯(O,O)氢键相连,形成三维网络。该结构作为双组分倒易孪晶进行精修。
