The asymmetric unit of title compound, C(15)H(9)ClF(2)O(3), consists of two crystallographically independent mol-ecules. The dihedral angle between the two terminal benzene rings in one mol-ecule is 7.92 (14)°, while that in the other mol-ecule is 73.50 (16)°. In the crystal, mol-ecules are stacked into columns along the b axis by inter-molecular C-H⋯O hydrogen bonds. A π-π inter-action with a centroid-to-centroid distance of 3.747 (2) Å further stabilizes the crystal structure.
标题化合物C(15)H(9)ClF(2)O(3)的不对称单元由两个晶体学独立的分子组成。一个分子中两个末端苯环之间的二面角为7.92 (14)°,而另一个分子中的二面角为73.50 (16)°。在晶体中,分子通过分子间C-H⋯O氢键沿b轴堆积成列。质心到质心距离为3.747 (2) Å的π-π相互作用进一步稳定了晶体结构。
