4-{Phen­yl[4-(6-phenyl-2,2'-bipyridin-4-yl)phen­yl]amino}­benzaldehyde

The title mol­ecule, C₃₅H₂₅N₃O, is a tri­phenyl­amine derivative with the 4-position substituted by an aldehyde group, and the 4'-position substituted by a 6-phenyl-2,2'-bi­pyridine group. The whole mol­ecule is non-planar and the dihedral angle between the core benzene and pyridine rings is 36.96 (5)°. The dihedral angle between the phenyl and benzaldehyde groups bonded to the amine N atom is 70.86 (5)°.
