Zinc fluoride

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