The title compd. belongs to the family of benzoannulated cyclobutenes. Crystallog. data and at. coordinates are given. Perfluorination of 1,2-dihydrocyclobutabenzene leads to essentially the same geometry as the parent hydrocarbon. The bond localization due to the Mills-Nixon effect in the direction of one of the Kekule forms cannot be found.
