Zinc fluoride (ZnF2
) is an inorganic chemical compound
. It is encountered as the anhydrous form and also as the tetrahydrate, ZnF2
O (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
, 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
*Reaction of hydrofluoric acid
with zinc, to yield hydrogen
) and zinc fluoride (ZnF2
Zinc fluoride can be hydrolysed by hot water to form the zinc hydroxyfluoride, Zn(OH)F.
