Zinc fluoride
Template:Short description Template:Chembox
Zinc fluoride is an inorganic chemical compound with the chemical formula Template:Chem2. It is encountered as the anhydrous form and also as the tetrahydrate, Template:Chem2 (rhombohedral crystal structure).[1] It has a high melting point and has the rutile structure containing 6 coordinate zinc, which suggests appreciable ionic character in its chemical bonding.[2] Unlike the other zinc halides, [[Zinc chloride|Template:Chem2]], [[Zinc bromide|Template:Chem2]] and [[Zinc iodide|Template:Chem2]], it is not very soluble in water.[2]
Like some other metal difluorides, Template:Chem2 crystallizes in the rutile structure, which features octahedral Zn cations and trigonal planar fluorides.[3]
Preparation and reactions
Zinc fluoride can be synthesized several ways.
- The reaction of zinc metal with fluorine gas.[2]
- Reaction of hydrofluoric acid with zinc, to yield hydrogen gas (Template:Chem2) and zinc fluoride (Template:Chem2).[2]
Zinc fluoride can be hydrolysed by hot water to form the zinc hydroxide fluoride, Zn(OH)F.[4]
The salt is believed to form both a tetrahydrate and a dihydrate.[5]
