Lithium hypofluorite is an inorganic compound with the chemical formula of LiOF. It is a compound of lithium, fluorine, and oxygen. This is a lithium salt of hypofluorous acid, and contains lithium cations Li and hypofluorite anions OF.

Synthesis

The salt theoretically results from the neutralization of hypofluorous acid (HOF) and lithium hydroxide (LiOH). It can be formed by the action of fluorine on lithium hydroxide:

6 F₂ + 6 LiOH → 2 LiF + O₂ + 4 LiOF + 6 HF

Chemical properties

The compound is quite unstable, since it contains oxygen in the oxidation state of 0. It, therefore, tends to decompose to lithium fluoride and oxygen gas:

2 LiOF → 2 LiF + O₂
