Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.043; wR factor = 0.112; data-to-parameter ratio = 16.3.In the title compound, C 13 H 18 ClNO 4 , the molecules are linked only by weak van der Waals interactions. The boat form of the six-membered ring is almost symmetric with respect to the epoxy bridge. The three five-membered rings adopt envelope conformations.
