Crystal structure of 1-(2-chloroacetyl)-2,6-bis(4-fluorophenyl)-3,3-dimethylpiperidin-4-one

Abstract

In the title molecule, C21H20ClF2NO2, the piperidine ring adopts a slightly distorted boat conformation. The two benzene rings form a dihedral angle of 87.43 (1)°. A weak intramolecular C—H...π interaction is observed. In the crystal, weak C—H...O hydrogen bonds and weak C—H...π interactions connect the molecules, forming a three-dimensional network.
