چکیده
In the title compound, C(23)H(23)NO(5), the C(5)N ring adopts an envelope conformation with a C atom as the flap, whilst the saturated C(6) ring fused to it adopts a chair conformation. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.

Crystal structure of 2-(2,4-diphenyl-3-azabicyclo[3.3.1]nonan-9-ylidene)acetonitrile
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.
