Alkali metal peroxides
Alkali metal peroxides are ionic compounds of the group 1 metals containing the peroxide anion O₂²⁻, powerful oxidizers used to scrub carbon dioxide from air in submarines.
Alkali-metal suboxides
Alkali-metal suboxides are metal-rich oxides of rubidium and cesium, built from ionic Rb₉O₂ and Cs₁₁O₃ clusters in a metallic matrix and classified as metallic electrides.
