Popis:	The crystal structures of two endo-endo-dienes, 5,6,7,8,9,9-hexachloro-1,4,4a,5,8,8a-hexahydro-endo-endo-1,4-ethano (and propano)-5,8-dimethanonaphthalene, 1b and 1c have been determined. These, together with the methano-homolog 1a (of known structure), are shown to exhibit decreasing across-space double-bond/double-bond repulsion which correlates with the observed decrease in the ease of cyclization in solution.
