Gold(III) fluoride, often represented by the chemical formula AuF3, is a chemical compound composed of gold (Au) cations with a +3 oxidation state and fluoride (F-) anions. It is one of the compounds in the gold-fluorine system and belongs to the class of gold halides.

Here are some key points about gold(III) fluoride:

1. Synthesis: Gold(III) fluoride can be prepared by reacting gold metal with fluorine gas or by oxidizing lower oxidation state gold compounds with fluorine.
2. Color and Properties: Gold(III) fluoride is typically pale yellow in color. Its properties are influenced by the presence of gold in the +3 oxidation state.
3. Applications: Gold(III) fluoride might find applications in chemical synthesis, catalysis, and potentially in electronic and optical devices, although its uses might be more limited compared to other gold compounds.
4. Research: Gold(III) fluoride might be of interest in the context of understanding the chemistry and properties of gold compounds with higher oxidation states, as well as in investigating its potential applications.
5. Coordination Chemistry: Gold(III) fluoride can serve as a ligand in coordination chemistry, forming complexes with various other metals and ligands.

Gold(III) fluoride’s applications are likely centered around its chemistry, and it might be of interest to researchers studying gold compounds, catalysis, and materials science. However, it’s worth noting that gold(III) fluoride might be less commonly encountered compared to other gold compounds with more well-established uses.
