rac-(2R*,3S*,5S*,6R*,7S*,8S*)-7,8-Dichlorobicyclo[2.2.2]octane-2,3,5,6-tetrayl tetraacetate

Abstract

The title compound, C(16)H(20)Cl(2)O(8), contains a central bicyclo[2.2.2] octane skeleton with slightly twisted conformation. In this structure, the C-C bond lengths are in the range 1.525 (2)-1.552 (2) angstrom. Two sides of this skeleton have cis,cis acetoxy substituents and the Cl atoms have a trans arrangement. An extensive network of weak C-H center dot center dot center dot O interactions stabilizes the crystal structure.
