Gold compounds are compounds by the element gold (Au). Although gold is the most noble of the noble metals , [ 1 ] [ 2 ] it still forms many diverse compounds. The oxidation state of gold in its compounds ranges from −1 to +5, but Au(I) and Au(III) dominate its chemistry.
The use of injected gold compound is indicated for rheumatoid arthritis. [4] Its uses have diminished with the advent of newer compounds such as methotrexate and because of numerous side effects. [4] The efficacy of orally administered gold is more limited than injecting the gold compounds. [5]

Organogold chemistry is the study of compounds containing gold–carbon bonds. They are studied in academic research, but have not received widespread use otherwise. The dominant oxidation states for organogold compounds are I with coordination number 2 and a linear molecular geometry and III with CN = 4 and a square planar molecular geometry.
Nitratoauric acid, hydrogen tetranitratoaurate, or simply called gold(III) nitrate is a crystalline gold compound that forms the trihydrate, HAu(NO 3) 4 ·3H 2 O or more correctly H 5 O 2 Au(NO 3) 4 ·H 2 O. [3] [2] This compound is an intermediate in the process of extracting gold. [4] In older literature it is also known as aurinitric acid. [5]

Gold(I) sulfide, Au 2 S. Formed by reaction of hydrogen sulfide with gold(I) compounds. Gold(III) sulfide, Au 2 S 3, claimed material but unsubstantiated. Gold tellurides: Au 2 Te 3, Au 3 Te 5, and AuTe 2 (approximate formulas) are known as non-stoichiometric compounds. They show metallic conductivity. Au 3 Te 5 is a superconductor at 1.62 K. [1]
Gold(V) fluoride is the inorganic compound with the formula Au 2 F 10. This fluoride compound features gold in its highest known oxidation state . This red solid dissolves in hydrogen fluoride but these solutions decompose, liberating fluorine.
