Lithium hypofluorite is an inorganic compound with the chemical formula of {{chem2|LiOF|auto=1}}. It is a compound of lithium, fluorine, and oxygen.{{cite book |title=Science Data Booklet |date=11 July 2020 |publisher=Manjunath.R |page=146 |url=https://books.google.com/books?id=ZG3wDwAAQBAJ&dq=%22Lithium+hypofluorite%22&pg=PA146 |access-date=12 May 2023 |language=en}}{{cite book |last1=Barin |first1=Ihsan |title=Thermochemical Data of Pure Substances: La-Zr |date=1995 |publisher=VCH |isbn=978-3-527-28745-1 |page=965 |url=https://books.google.com/books?id=IUgpAAAAYAAJ&q=Lithium+hypofluorite |access-date=12 May 2023 |language=en}}{{cite book |last1=Binnewies |first1=M. |last2=Milke |first2=E. |title=Thermochemical Data of Elements and Compounds |date=3 December 2002 |publisher=Wiley |isbn=978-3-527-30524-7 |page=466 |url=https://books.google.com/books?id=qUJRAAAAMAAJ&q=Lithium+hypofluorite+LiOF |access-date=12 May 2023 |language=en}} This is a lithium salt of hypofluorous acid,{{cite web |title=NIST-JANAF Themochemical Tables, Fourth Edition |url=https://webbook.nist.gov/cgi/cbook.cgi?ID=C34240841&Mask=1 |publisher=NIST |access-date=12 May 2023 |pages=1–1951 |date=1998}} and contains lithium cations {{chem2|Li+}} and hypofluorite anions {{chem2|−OF}}.{{dubious|date=February 2025}}
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:
:{{chem2|HOF + LiOH → LiOF + H2O}}
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:
:{{chem2|2 LiOF → 2 LiF + O2}}
