This is the fourth member of the polyoxidanes. The first three are water [(mon)oxidane],hydrogen peroxide (dioxidane), andtrioxidane. Tetraoxidane is more unstable than the previous compounds. The term "tetraoxidane" extends beyond the parent compound to several daughter compounds of the general formulaR 2O 4, where R can be hydrogen, halogen atoms, or various inorganic and organic monovalent radicals. The two Rs together can be replaced by a divalent radical, so heterocyclic tetraoxidanes also exist.[7]
