1-Chloroacetyl-2,6-bis(2-chlorophenyl)-3,5-dimethylpiperidin-4-one oxime

Abstract

In the title compound, C21H21Cl3N2O2, the piperidine ring adopts a distorted boat conformation. One of the chlorophenyl rings is almost perpendicular to the best plane through piperidine ring, making a dihedral angle of 88.7 (1)°, whereas the other ring is twisted by 71.8 (1)°. The crystal packing is stabilized by intermolecular C—H...O, C—H...Cl and O—H...O interactions.
