Zinc fluoride (ZnF2) is an inorganic chemical compound. It is encountered as the anhydrous form and also as the tetrahydrate, ZnF2 ยท 4H2O (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, ZnCl2, ZnBr2 and ZnI2, 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 (H2) and zinc fluoride (ZnF2). Zinc fluoride can be hydrolysed by hot water to form the zinc hydroxyfluoride, Zn(OH)F.
