3-Chloro-r-2,c-6-bis--(4-fluoro-phen-yl)-3-methyl-piperidin-4-one

摘要

The title compound, C18H16ClF2NO, contains one independent mol-ecule in the asymmetric unit, with the piperidin-4-one ring adopting a slightly distorted chair conformation and an equatorial orientation of all the substituents except chlorine. A single weak inter-molecular C—H?O inter-action influences the crystal packing, forming infinite one-dimensional zigzag chains along the?a?axis. The structure was refined as a two-component inversion twin.
