Popis:	In the title compound, endo-endo-syn-1,7,8,9,10,16,17,18-octachloro-19,19,20,20-tetramethoxy-4,13-dioxapentacyclo[14.2.1.1 7,10 .0 2,15 .0 6,11 ]icosa-8,17-diene, C 22 H 24 Cl 8 O 6 , the ten-membered ring adopts a chair-chair conformation. The near-zero endocyclic torsion angles of this ring at the ring fusion bonds have values of 0.0 (6) and -0.8 (4) o . The norbornene C=C bonds have lengths 1.320 (4) and 1.311 (5) A. The four dioxolane O-C bonds have an average length of 1.413 (2) A
