Cobalt(II) fluoride
Cobalt(II) fluoride is an inorganic compound with the formula CoF2. It is a pink paramagnetic solid. Like some other metal difluorides, CoF2 crystallizes in the rutile structure, which features octahedral Co centers and planar fluorides.
Treating anhydrous cobalt chloride with hydrogen fluoride gives cobalt(II) fluoride:
Tetrahydrated cobalt(II) fluoride is formed by dissolving cobalt(II) in hydrofluoric acid. The anhydrous fluoride can be extracted from this by dehydration. Other synthesis can occur at higher temperatures.
Cobalt(II) fluoride reacts with fluorine to give cobalt(III) fluoride:
The latter is a catalyst for fluorination reactions.
