Lithium superoxide is extremely reactive because of the odd number of electrons present in the π* molecular orbital of the superoxide anion. [4] Matrix isolation techniques can produce pure samples of the compound, but they are only stable at 15-40 K. [3] At higher (but still cryogenic) temperatures, lithium superoxide can be produced by ...
Crystal structure of potassium superoxide. Lithium superoxide (LiO 2) has only been isolated in matrix isolation at 15 K. Sodium superoxide (NaO 2) is a yellow-orange solid that melts at 551.7 °C. It is made by the high-pressure oxidation of sodium peroxide. Potassium superoxide (KO 2) is a yellow solid that
Lithium peroxide is the inorganic compound with the formula Li 2 O 2. Lithium peroxide is a white solid, and unlike most other alkali metal peroxides, it is nonhygroscopic . Because of its high oxygen:mass and oxygen:volume ratios, the solid has been used to remove CO 2 from and release O 2 to the atmosphere in spacecraft .

Lithium oxide (Li 2 O) or lithia is an inorganic chemical compound. It is a white solid. Although not specifically important, many materials are assessed on the basis of their Li 2 O content. For example, the Li 2 O content of the principal lithium mineral spodumene (LiAlSi 2 O 6) is 8.03%. [2]
Lithium monoxide anion (LiO −) is a superbase existing in the gas phase. It was the strongest known base until 2008, when the isomeric diethynylbenzene dianions were determined to have a higher proton affinity. The methanide ion CH − 3 was the strongest known base before lithium monoxide anion was discovered. [2] LiO − has a proton ...
Suboxides are a class of oxides wherein the electropositive element is in excess relative to the “normal” oxides. [1] When the electropositive element is a metal, the compounds are sometimes referred to as “metal-rich”.
Lithium oxalate is an organic compound with the chemical formula Li 2 C 2 O 4. It is a salt of lithium metal and oxalic acid. [3] [4] It consists of lithium cations Li + and oxalate anions C 2 O 2− 4. Lithium oxalate is soluble in water and converts to lithium oxide when heated. [5]
