title: Crystal structure of 2-(2,4-diphenyl-3-aza-bicyclo-[3.3.1]nonan-9-yl-idene)aceto-nitrile.
abstract: In the title 3-aza-bicyclo-nonane derivative, C22H22N2, both the fused piperidine and cyclo-hexane rings adopt a chair conformation. The phenyl rings attached to the central aza-bicylononane fragment in an equatorial orientation are inclined to each other at 23.7 (1)°. The amino group is not involved in any hydrogen bonding, so the crystal packing is stabilized only by van der Waals forces.
