The title piperidine derivative, C26H26N2O3, has an E conformation about the N=C bond. The piperidine ring has a chair conformation and its mean plane is almost perpendicular to the attached phenyl rings, making dihedral angles of 87.47 (9) and 87.34 (8)°. The planes of these two phenyl rings are inclined to one another by 60.38 (9)°. The plane of the terminal phenyl ring is tilted at an angle of 32.79 (9)° to the mean plane of the piperidine ring. The mol-ecular conformation is stabilized by two intra-molecular C-H⋯O contacts. There are no significant inter-molecular inter-actions in the crystal.
标题哌啶衍生物C₂₆H₂₆N₂O₃中，N = C键具有E构型。哌啶环呈椅式构象，其平均平面几乎垂直于相连的苯环，二面角分别为87.47 (9)°和87.34 (8)°。这两个苯环的平面相互倾斜60.38 (9)°。末端苯环的平面相对于哌啶环的平均平面倾斜32.79 (9)°。分子构象通过两个分子内C—H⋯O接触得以稳定。晶体中不存在显著的分子间相互作用。
