AbstractThe title molecule, C23H31NO, has two alternative cyclohexanone configurations at the 4-position in a ratio of 0.663 (3):0.337 (3). The plane of the five-membered planar ring in the indolin-2-ylidene subtends an angle of 2.19 (7)° with its fused aromatic ring, an angle of 16.24 (8)° with the plane of the major cyclohexanone configuration and an angle of 8.54 (15)° with the bridging planar ethylidene C atoms. These last atoms subtend an angle of 8.37 (16)° with the mean plane through the major cyclohexanone configuration. The molecules pack approximately parallel to the (101) plane via C-H⋯π and C-H⋯O interactions.
