title: Crystal structure of 1-(2-chloro-acet-yl)-2,6-bis-(4-fluoro-phen-yl)-3,3-di-methyl-piperidin-4-one.
abstract: In the title mol-ecule, C21H20ClF2NO2, the piperidine ring adopts a slightly distorted boat conformation. The two benzene rings form a dihedral angle of 87.43 (1)°. A weak intra-molecular C-H⋯π inter-action is observed. In the crystal, weak C-H⋯O hydrogen bonds and weak C-H⋯π inter-actions connect the mol-ecules, forming a three-dimensional network.
