(1RS,3SR,4RS,5RS,7SR,9SR)-4,7-Diacetyl-9-hydroxy-1,3,5,9-tetramethyl-2,6,8-trioxatricyclo[3.2.1.1^3,7]nonane: a Tricyclic System Formed Under Cathodic Conditions

The title compound, C₁₄H₂₀O₆, generated from a bicyclic precursor under electrochemical conditions, crystallizes with six identical molecules in the asymmetric unit. Comparison of equivalent bond lengths and angles reveals no major structural differences between the molecules. However, the intermolecular distances suggest that the molecular packing is due to pairwise attractive interactions between the species, resulting in three different types of dimers. The crystal lattice can be described as a layer structure with strata either perpendicular or parallel to the ac plane.
