title: 2,5-Bis{2,2-bis-[4-(dimethyl-amino)-phen-yl]ethen-yl}-N,N'-diphenyl-N,N'-dipropyl-benzene-1,4-diamine.
abstract: The title compound, C(60)H(68)N(6), was prepared by Horner olefination of a terephthaldialdehyde and a diaryl-methyl phospho-nate. There is one half-mol-ecule, located on an inversion centre, in the asymmetric unit. The dihedral angle between the plane of the vinyl-ene unit and the central ring is 36.79 (15)°, while those between the vinyl-ene unit and the lateral phenyl rings are 53.04 (10) and 53.74 (9)°.
