The crystal structure of the title compound, ethylenetetrayltetrakis[dimethyl(4-phenyl)amine] hemibenzene solvate, C34H40N4.0.5C6H6, has been determined by X-ray diffraction at 200 K. The molecular halves of the tetrasubstituted ethylene subunit are twisted by 12.0 (2)° around the ethylene C=C bond. Two of the p-dimethylamino groups are pyramidal and twisted by 21.3 (2) and 20.8 (3)° out of the planes of the attached phenyl rings, whereas the other two are almost coplanar with their attached phenyl rings. All structural parameters support an extensive electron delocalization over at least two of the four p-dimethylaminophenyl substituents.
