Abstract

The title compound, C(13)H(16)O(2), is a chiral bicyclic structure composed of two fused cyclo-hexa-ne rings possessing both boat and chair conformations. The mol-ecules are packed in enantio-pure columns which are pairwise linked forming an overall racemic solid; within the column pairs the packing is governed by weak dipole-dipole inter-actions stemming from stacked carbonyl functionalities (CO(centroid)-CO(centroid) distance = 3.290 Å).
