Abstract

In the title piperidine derivative, C21H22Cl2N2O, the piperidine ring adopts a chair conformation. The chloro-phenyl rings are oriented at an angle of 45.59 (14)° with respect to each other. In the crystal, mol-ecules 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 inter-actions present. The crystal studied was refined as an inversion twin.

Keywords: N—H⋯O hydrogen bonds; N—H⋯π inter­actions; crystal structure; piperidine derivatives
