Torturing the 7-Oxabicyclo[2.2.1]heptane Skeleton with an Oxetane Ring: 4,7-Dioxatricyclo[3.2.1.0^3,6]octane at 190K

The low temperature phase of 4,7-dioxatricyclo[3.2.1.0^3,6]octane, C₆H₈O₂, has been structurally characterized by X-ray diffraction at 190 K. Only minor bond differentiation is observed here compared to oxetane and 7-oxabicylo[2.2.1]heptanes.
