title: Crystal structure of trans-1-{2-[4-(di-methyl-amino)-phen-yl]eth-yl}-4-[2-(pyren-1-yl)eth-yl]cyclo-hexa-ne.
abstract: The title compound, C34H37N, is a pyrene derivative in which the pyrene ring system is linked to an ethyl-cyclo-hexane unit which, in turn, carries a [4-(di-methyl-amino)-phen-yl]ethyl substituent in the para position. The central cyclo-hexane ring has a chair conformation, with the exocyclic C-C bonds in equatorial orientations. The benzene ring is inclined to the mean plane of the pyrene ring system [maximum deviation = 0.038 (4) Å] by 14.84 (15)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming chains propagating along [010]. The crystal was refined as a non-merohedral twin [domain ratio = 0.9989 (4):0.0011 (4)].
