4-(6-Benzyl-7-oxo-1,2,3,4,5,5a,5a1,6,7,7a,8,12b-dodecahydrobenzo[f]cycloocta[cd]isoindol-8-yl)benzonitrile

Abstract

In the title compound, C31H30N2O, the cis-fused cyclohexene and cyclooctane rings adopt boat and boat-chair conformations, respectively. The essentially planar five-membered N-heterocyclic ring [r.m.s. deviation = 0.017 (1) Å] is cis- and trans-fused, respectively, with the cyclohexene and cyclooctane rings. In the crystal, molecules are linked into inversion dimers through pairs of weak C—H...O interactions.
