The title compound, C26H32, was retrieved as one of three products from the reaction of tert-butyllithium with 11,12-dimethylene-9,10-dihydroethenoanthracene and 4,5-diiodopentacyclo[4.3.0.02,4.03,8.05,7]nonane. The structure shows the expected ethenoanthracene geometry with molecules arranged via van der Waals surfaces.
