In the title compound, C26H24, the central cyclooctatetraene ring has a boat conformation, and the Roller Tool molecule is saddle shaped.The seat is defined by the mean plane of the four-atom attachment points (r.m.s.deviation = 0.

014 Å) of the two bicycloheptane substituents.These substituents comprise the pommel Brain Supplements and cantle, with each mean plane defined by four atoms proximate to the seat (r.m.s.deviations = 0.

001 and 0.000 Å).Relative to the seat, the pommel and cantle bend up 33.36 (5) and 34.22 (4)°, while the benzo units (flaps, r.

m.s.deviations = 0.008 and 0.013 Å) bend down 33.

48 (4) and 36.58 (4)°.
