The chemical compound 135-trioxanetrione or 135-trioxacyclohexane-246-trione is a hypothetical oxide of carbon with formula C3O6. It can be considered a cyclic trimer of carbon dioxide (CO2) or as a triple ketone of 135-trioxane (135-trioxacyclohexane).Theoretical calculations indicate that the compound is unstable at room temperature (half-life less than 8 seconds); but may be stable at -196 °C.
