Abstract
In the title piperidine derivative, C21H22Cl2N2O, the piperidine ring adopts a chair conformation. The chlorophenyl rings are oriented at an angle of 45.59 (14)° with respect to each other. In the crystal, molecules are linked via N—H⋯O hydrogen bonds, forming C(4) chains along [100]. The chains are linked by C—H⋯O hydrogen bonds, forming sheets parallel to the ab plane. Within the sheets, there are N—H⋯π interactions present. The crystal studied was refined as an inversion twin.
