Abstract: The syntheses and crystal structure of 3-chloro-3-methyl-r-2,c-6-di­phenyl­piperidin-4-one, C18H18ClNO, (I), 3-chloro-3-methyl-r-2,c-6-di-p-tolyl­piperidin-4-one, C20H22ClNO, (II), and 3-chloro-3-methyl-r-2,c-6-bis­(4-chloro­phen­yl)piperidin-4-one, C18H16Cl3NO, (III), are described. In each structure, the piperidine ring adopts a chair conformation and dihedral angles between the mean planes of the phenyl rings are 58.4 (2), 73.5 (5) and 78.6 (2)° in (I), (II) and (III), respectively. In the crystals, mol­ecules are linked into C(6) chains by weak N—H⋯O hydrogen bonds and C—H⋯π inter­actions are also observed
