2,3,4,5,7,7,8,8,-Octafluorobicyclo[4.2.0]octa-1,3,5-triene at 125K

The title compound belongs to the family of benzo-annulated cyclobutenes. Perfluorination of 1,2-dihydrocyclobutabenzene leads to essentially the same geometry as the parent hydrocarbon. Bond localization due to the Mills-Nixon effect in the direction of one of the Kekule forms cannot be found.
