چکیده
In the title compound, C(27)H(25)NO, the piperidine ring adopts an envelope conformation with the N atom at the flap position. The two benzylidene-benzene rings are oriented at a dihedral angle of 8.5 (1)°. In the crystal, the mol-ecules are linked into centrosymmetric dimers by pairs of inter-molecular C-H⋯O hydrogen bonds. The dimers are connected via C-H⋯π inter-actions involving the phenyl rings.
