In the title compound, C16H12F2O3, the plane of the phenyl ring makes a dihedral angle of 3.22 (8)° with that of the benzene ring. The mol-ecule has an E conformation about the C=C bond. In the crystal, mol-ecules are linked via pairs of O-H⋯O hydrogen bonds, forming inversion dimers which are further consolidated by a pair of C-H⋯O hydrogen bonds. The dimers are linked via C-H⋯O hydrogen bonds, forming columns along the b-axis direction.
在标题化合物C₁₆H₁₂F₂O₃中，苯环平面与苯环平面形成的二面角为3.22 (8)°。分子关于C=C键呈E构型。在晶体中，分子通过O-H⋯O氢键对相连，形成反演二聚体，该二聚体又通过一对C-H⋯O氢键进一步巩固。这些二聚体通过C-H⋯O氢键相连，沿b轴方向形成柱体。
