چکیده
In the title moleclue, C(19)H(21)NO, the 4-piperidone ring adopts a chair conformation in which the two benzene rings and the methyl group attached to C atoms all have equatorial orientations. In the crystal structure, centrosymmetric dimers are formed through weak inter-molecular C-H⋯O hydrogen bonds [the dihedral angle between the aromatic rings is 58.51 (5)°].

In the title compound, C(21)H(21)Cl(2)NO(2), the piperidine ring adopts a distorted boat conformation. The two phenyl rings are approximately perpendicular to each other, with a dihedral angle of 86.12 (7)°. Mol-ecules are linked into centrosymmetric dimers by pairs of bifurcated C-H⋯O hydrogen bonds, forming R(2) (2)(10) and R(2) (2)(14) ring motifs, and an intramolecular C-H⋯O link also occurs.
