在标题化合物C14 H10 F2 O的晶体结构中，两个晶体学上独立的分子中苯环之间的二面角为46.9（2）和47.6（2）°。 分子间通过C-H-F相互作用连接成二聚体，二聚体通过苯环间的π-π相互作用沿B轴沿着方向堆积成柱状[质心-质心距离= 3.8221 π，环平面间二面角为4.87（2）°]。 此外，C-F π相互作用也有助于晶体堆积（C π质心距离= 3.5919 π）。
In the crystal structure of the title compound, C14H10F2O, the dihedral angles between the benzene rings in the two crystallographically independent molecules are 46.9 (2) and 47.6 (2)°. The molecules are linked into dimers by C—H⋯F interactions and these dimers are further stacked into columns along the b axis by π–π interactions between the benzene rings [centroid–centroid distance = 3.8221 Å; the dihedral angle between the planes of these rings is 4.87 (2)°]. In addition, C—F⋯π interactions also contribute to the crystal packing (C⋯centroid distance = 3.5919 Å).
