【 摘 要 】

The title compound, C23H29N3O, was synthesized from the condensation reaction of 8-hy­droxy­julolidine-9-carbaldehyde and N,N-diethyl-p-phenyl­enedi­amine. The hy­droxy group forms a intra­molecular hydrogen bond to the imine N atom and generates an S(6) ring motif. The conformation about the C=N bond is E, and the aromatic ring of the julolidine moiety is inclined to the benzene ring by 3.74 (14)°. One of the fused non-aromatic rings of the julolidine moiety adopts an envelope conformation and the other has a screw-boat conformation. In the crystal, mol­ecules are linked by C—H⋯π inter­actions involving the aromatic julolidine ring, forming slabs parallel to the bc plane. The tricyclic fragment of the julolidine ring and the azomethine C=N bond are disordered over two sets of sites with a refined occupancy ratio of 0.773 (3):0.227 (3).
