1,3-Dimethyl-2,6-Diphenyl-Piperidin-4-one

Abstract

In the title moleclue, C19H21NO, 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)°].
