Chemical compound

Lithium hypofluorite is an inorganic compound with the chemical formula of LiOF. It is a compound of lithium, fluorine, and oxygen.^[1]^[2]^[3] This is a lithium salt of hypofluorous acid.^[4], 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
