title: Crystal structure of (1R,2S,4R,7R,8S,9R)-3,3-dichloro-8,9-epoxy-4,8,12,12-tetramethyltricyclo[5.5.0.0(2,4)]dodecane.
abstract: The title compound, C16H24Cl2O, is built up from two fused six- and seven-membered rings which bear a di-chloro-cyclo-propane group and an ep-oxy group, respectively. In the mol-ecule, the six-membered ring adopts an envelope configuration with the C atom linking the ep-oxy ring at the flap, while the seven-membered ring adopts a boat-sofa conformation.
