Abstract

In the title compound, C₃₆H₄₂O₈, the dioxolane ring adopts a twist conformation; the two adjacent C atoms deviate alternately from the mean plane of other atoms by - 0.287 (5) and 0.174 (5) Å. The cyclohexane, cyclohexadiene and central cyclooctane rings show chair, half-chair and boat-chair forms, respectively. As a result of the strained ring system, the tetrasubsituted olefin in the cyclohexadiene is skewed from an ideal planar structure. In the crystal, C - H⋯O hydrogen bonds connect the molecules into a sheet parallel to (100). The sheets are further linked by other weak C - H⋯O and C - H⋯π interactions, forming a three-dimensional network.
