Abstract

In the title compound, C(21)H(16)F(2)O(3), the pendant fluoro-benzene rings form dihedral angles of 22.22 (12) and 50.74 (11)° with the central benzene ring. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds into chains along the a axis. The crystal structure also features C-H⋯π inter-actions.

摘要

在标题化合物C₂₁H₁₆F₂O₃中，悬挂的氟苯环与中心苯环形成的二面角分别为22.22 (12)°和50.74 (11)°。在晶体中，分子通过C—H⋯O氢键沿a轴连接成链。晶体结构还具有C—H⋯π相互作用。
