2,4-Bis(4-chlorophenyl)-1-methyl-3-azabicyclo[3.3.1]nonan-9-one

Abstract

The title compound, C21H21Cl2NO, exists in a twin-chair conformation with an equatorial orientation of the 4-chlorophenyl groups on both sides of the secondary amino group; the dihedral angle between the 4-chlorophenyl rings is 36.58 (2)°. The crystal packing is stabilized by an intermolecular N—H...O hydrogen bond and a weak Cl...Cl [3.4331 (9) Å] interaction.
