چکیده
In the title compound, C20H22ClNO, the piperidine ring has a twist-boat conformation. There is an intra-molecular C-H⋯π inter-action involving the two phenyl rings which are inclined to one another by 84.91 (7)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming helical chains along [010]. The chains are linked by C-H⋯π inter-actions, forming sheets parallel to (100).
