Gold halides are compounds of gold with the halogens.
Beaconsfield is a former gold mining town near the Tamar River, in the north-east of Tasmania, Australia. It lies 40 kilometres north of Launceston on the West Tamar Highway. It is a rural and residential locality in the local government areas (LGA) of West Tamar and Latrobe in the Launceston and North-west and west LGA regions of Tasmania. The 2016 census has a population of 1298 for the state suburb of Beaconsfield.
Gold(V) fluoride is the inorganic compound with the formula Au2F10. This fluoride compound features gold in its highest known oxidation state. This red solid dissolves in hydrogen fluoride but these solutions decompose, liberating fluorine.
Tetraxenonogold(II), gold tetraxenide(II) or AuXe2+
4 is a cationic complex with a square planar configuration of atoms. It is found in the compound AuXe2+
4(Sb
2F−
11)
2 (tetraxenonogold(II) undecafluorodiantimonate), which exists in triclinic and tetragonal crystal modifications. The AuXe2+
4 ion is stabilised by interactions with the fluoride atoms of the counterion. The Au−Xe bond length is 274 pm (2.74 Å). Tetraxenonogold(II) is unusual in that it is a coordination complex of xenon, which is weakly basic. It is also unusual in that it contains gold in the +2 oxidation state. It can be produced by reduction of AuF3 by xenon in the presence of fluoroantimonic acid. The salt crystallises at low temperature. Four xenon atoms bond with the gold(II) ion to make this complex.
Gold(III) fluoride, AuF3, is an orange solid that sublimes at 300 °C. It is a powerful fluorinating agent. It is very sensitive to moisture, yielding gold(III) hydroxide and hydrofluoric acid.

A hexafluoride is a chemical compound with the general formula QXnF6, QXnF6m−, or QXnF6m+. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H2SiF6), which is a byproduct of the mining of phosphate rock. In the nuclear industry, uranium hexafluoride (UF6) is an important intermediate in the purification of this element.
Bismuth fluoride may refer to:
Iron fluoride may refer to:
Trifluorides are compounds in which one atom or ion has three fluorine atoms or ions associated. Many metals form trifluorides, such as iron, the rare-earth elements, and the metals in the aluminium and scandium columns of the periodic table. Most metal trifluorides are poorly soluble in water except Ferric fluoride and Indium(III) fluoride, but several are soluble in other solvents.
Gold heptafluoride is a gold(V) compound with the empirical formula AuF7. The synthesis of this compound was first reported in 1986. However, current calculations suggest that the structure of the synthesized molecule was actually a difluorine ligand on a gold pentafluoride core, AuF5·F2. That would make it the first difluorine complex and the first compound containing a fluorine atom with an oxidation state of zero. The gold(V)–difluorine complex is calculated to be 205 kJ/mol more stable than gold(VII) fluoride. The vibrational frequency at 734 cm−1 is the hallmark of the end-on coordinated difluorine molecule.
Australia is one of many countries that have water fluoridation programs currently operating. As of March 2012, artificially fluoridated drinking water is administered to 70% or more of the population in all states and territories. The acceptance of the benefits of water fluoridation occurred in Australia in December 1953, roughly two years after acceptance in the United States. Many of Australia's drinking water supplies subsequently began fluoridation in the 1960s and 1970s. By 1984 almost 66% of the Australian population had fluoridated drinking water, represented by 850 towns and cities. Some areas within Australia have natural fluoride levels in the groundwater, which was estimated in 1991 to provide drinking water to approximately 0.9% of the population.
Gold(I) fluoride is the inorganic compound with the formula AuF. The solid has eluded isolation, but its existence has been observed by rotational spectroscopy and mass spectrometry as a gas.
Silver(III) fluoride, AgF3, is an unstable, bright-red, diamagnetic compound containing silver in the unusual +3 oxidation state. Its crystal structure is very similar to that of gold(III) fluoride: it is a polymer consisting of rectangular AgF4 units linked into chains by fluoro bridges.
Tetraoxygen difluoride is an inorganic chemical compound of oxygen, belonging to the family of oxygen fluorides. It consists of two O2F units bound together with a weak O-O bond, and is the dimer of the O2F radical.
