title: 2,4-Bis(4-chloro-phen-yl)-1-methyl-3-aza-bicyclo-[3.3.1]nonan-9-one.
abstract: The title compound, C(21)H(21)Cl(2)NO, exists in a twin-chair conformation with an equatorial orientation of the 4-chloro-phenyl groups on both sides of the secondary amino group; the dihedral angle between the 4-chloro-phenyl rings is 36.58 (2)°. The crystal packing is stabilized by an inter-molecular N-H⋯O hydrogen bond and a weak Cl⋯Cl [3.4331 (9) Å] inter-action.
