Dibenzo[a,e]penta­cyclo­[12.2.1.1^6,9.0^2,13.0^5.10]octa­deca-2(13),5(10)-diene

In the title compound, C₂₆H₂₄, the central cyclo­octa­tetra­ene ring has a boat conformation, and the 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 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)°.

S1. Comment

The central 8-ring of the title compound adopts the boat configuration, and the overall shape of the molecule is that of a saddle. Relative to the mean plane of the saddle seat (C07, C08, C15, C16, δ_r.m.s. = 0.014 Å), the two bicycloheptane moieties (mean planes C07, C08, C22, C24, δ_r.m.s. = 0.001 Å, and C15, C16, C17, C19, δ_r.m.s. = 0.000 Å) bend up 33.36 (5)° and 34.22 (4)°, while the mean planes of the benzo moieties (C01 – C06, δ_r.m.s. = 0.008. and C09 – C14, δ_r.m.s. = 0.013 Å) bend down 33.48 (4)° and 36.58 (4)°.

S2. Experimental

The preparation is described by Schaller (1994). Suitable crystals were obtained by recrystallization from benzene.

S3. Refinement

All H atoms were placed in calculated positions, guided by difference maps, with C—H bond distances 0.95 (aromatic C) and 0.99 (alkyl C) Å, and U_iso=1.2U_eq, thereafter refined as riding.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
