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

Abstract

The asymmetric unit of the title compound, C24H23NO, contains two crystallographically independent molecules (A and B). In both molecules, the piperidine rings adopt a chair conformation and the phenyl rings and the benzyl group substituents are attached equatorially. The dihedral angle between the phenyl rings is 60.80 (10) in molecule A and 68.43 (9) in molecule B. The phenyl ring of the benzyl group makes dihedral angles of 76.95 (9) and 42.25 (10) with the phenyl rings in molecule A, and dihedral angles of 81.38 (11) and 30.19 (11) in molecule B. In the crystal, the two molecules are linked by N—H⋯O hydrogen bonds, forming –A–B–A–B– chains along [100]. In addition, five C—H⋯π interactions are also present, linking the chains to form a three-dimensional structure.
