c-3,t-3-Dimethyl-r-2,c-6-diphenylpiperidin-4-one

In the title compound, C19H21NO, the piperidine ring adopts a chair conformation. The two phenyl rings attached to the piperidine ring at 2 and 6 positions occupy equatorial orientations and the dihedral angle between them is 57.53 (11)°. In the crystal, the molecules are connected via weak intermolecular C—H...π interactions, leading to a zigzag chains
