Abstract: Reaction of tert-butyllithium with 11,12-dimethylene-9,10-dihydro-9,10-ethanoanthracene and 4,5-diiodopentacyclo[4.3.0.0^2,4.0^3,8.0^5,7]nonane gives three products, one of which crystallizes from petroleum ether as the title compound, C₄₄H₄₆, (I). Molecules of (I) are positioned on inversion centers (Z' = 0.5) in the space group P2₁/n and lack any discernible intermolecular interactions.
