Lithium oxide is formed along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen: :4Li + → 2. Pure can be produced by the thermal decomposition of lithium peroxide, , at 450 °C〔 :2 → 2 + ==Structure== In the solid state lithium oxide adopts an antifluorite structure which is related to the , fluorite structure with Li cations substituted for fluoride anions and oxide anions substituted for calcium cations. The ground state gas phase molecule is linear with a bond length consistent with strong ionic bonding.〔Wells A.F.
