(3E,5E)-3,5-Bis(4-methyl-benzyl-idene)-1-[3-(piperidin-1-yl)propano-yl] piperidin-4-one

Abstract

In the title compound, C29H34N2O2, the central piperidine ring adopts a half-chair conformation, whereas the terminal one adopts a chair conformation. The mean plane of the central piperidine ring [maximum deviation = 0.384 (2) Å] makes dihedral angles of 64.82 (13) and 17.55 (13)°with the benzene rings. In the crystal, mol-ecules are linked into a tape along the b axis via C-H⋯O inter-actions, generating R 2 2(20) and R 2 1(6) graph-set motifs. C-H⋯π inter-actions are observed between the tapes.
