Zinc fluoride (
ZnF2) is an
inorganic chemical compound. It is encountered as the anhydrous form and also as the tetrahydrate, ZnF
2 ยท 4H
2O (rhombohedral crystal structure). It has a high melting point and has the
rutile structure containing 6 coordinate zinc, which suggests appreciable ionic character in its chemical bonding.
Unlike the other zinc halides, ZnCl
2, ZnBr
2 and ZnI
2, it is not very soluble in water.
Preparation and reactions
Zinc fluoride can be synthesized several ways.
*Reaction of a
fluoride salt with
zinc chloride, to yield zinc fluoride and a chloride salt, in aqueous solution.
*The reaction of
zinc metal with
fluorine gas.
*Reaction of
hydrofluoric acid with zinc, to yield
hydrogen gas (H
2) and zinc fluoride (ZnF
2).
Zinc fluoride can be hydrolysed by hot water to form the zinc hydroxyfluoride, Zn(OH)F.
