In the title molecule, C23H21NO, the piperidine ring adopts a chair conformation, with the N and carbonyl C atoms as flaps, which deviate on either side bar drain board of the chair by −0.706 (3) and 0.494 (3) Å, respectively.All three phenyl rings are in equatorial positions on the animationbengal.com piperidine ring, making angles with the puckering plane of 73.

5 (1), 73.1 (1) and 67.2 (1)°.Though there is no classical hydrogen bonding, the crystal is stabilized by intermolecular C—H.

π contacts and π–π stacking interactions involving phenyl rings [centroid–centroid distance = 4.424 (2) Å].
