In the title mol-ecule, C21H20ClF2NO2, the piperidine ring adopts a slightly distorted boat conformation. The two benzene rings form a dihedral angle of 87.43 (1)°. A weak intra-molecular C-H⋯π inter-action is observed. In the crystal, weak C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions connect the mol-ecules, forming a three-dimensional network.
在标题分子C₂₁H₂₀ClF₂NO₂中，哌啶环呈轻微扭曲的船式构象。两个苯环形成的二面角为87.43 (1)°。观察到一个弱的分子内C—H⋯π相互作用。在晶体中，弱的C—H⋯O氢键和弱的C—H⋯π相互作用连接分子，形成三维网络。
