It can be considered a cyclic dimer of carbon dioxide (CO2) or as a double ketone of 1,3-dioxetane (1,3-dioxacyclobutane). Theoretical calculations indicate that the compound would be extremely unstable at room temperature (half-life of less than 1.1 μs) but may be stable at −196 °C.Errol Lewars (1996), Polymers and oligomers of carbon dioxide: ab initio and semiempirical calculations.
