Structure of N-Nitroso-2,4-diphenyl-3-azabicyclo[3.3.1]nonane

The title compound adopts a twin-chair conformation. The overall conformation is similar in both the molecules of the asymmetric unit. The phenyl rings are equatorially disposed with respect to the central ring system. The plane of the nitroso group makes angles of 31.0 (4) and 33.4 (5)° with the C(2)-N(3)-C(4) plane of the piperidine ring in molecules A and B, respectively. The $N(3)\cdot\cdot\cdot C(7)$ non-bonded separation is 3.19 (7) \AA for both molecules A and B. The crystal structure is stabilized by van der Waals interactions.
