Most drugs based on gold are Au(I) derivatives. [3] Au(III) (referred to as the auric) is a common oxidation state, and is illustrated by gold(III) chloride, Au 2 Cl 6. The gold atom centers in Au(III) complexes, like other d 8 compounds, are typically square planar, with chemical bonds that have both covalent and ionic character. Gold(I,III ...
Gold(III) chloride is the starting point for the chemical synthesis of many other gold compounds. For example, the reaction with potassium cyanide produces the water-soluble complex, K[Au(CN) 4]: [20] AuCl 3 + 4 KCN → K[Au(CN) 4] + 3 KCl. Gold(III) fluoride can be also produced from gold(III) chloride by reacting it with bromine trifluoride. [15]
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(III) oxide (Au 2 O 3) is an inorganic compound of gold and oxygen with the formula Au 2 O 3. It is a red-brown solid that decomposes at 298 °C. [3] According to X-ray crystallography, Au 2 O 3 features square planar gold centers with both 2- and 3-coordinated oxides. The four Au-O bond distances range from 193 to 207 picometers. [1]
Group 11, by modern IUPAC numbering, [1] is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), gold (Au), and roentgenium (Rg), although no chemical experiments have yet been carried out to confirm that roentgenium behaves like the heavier homologue to gold.

[3] [4] [5] It has the empirical formula AuBr 3, but exists as a dimer with the molecular formula Au 2 Br 6 in which two gold atoms are bridged by two bromine atoms. [4] [5] [6] It is commonly referred to as gold(III) bromide, gold tribromide, and rarely but traditionally auric bromide, and sometimes as digold hexabromide. The analogous copper ...
Gold(III) hydroxide, gold trihydroxide, or gold hydroxide is an inorganic compound, a hydroxide of gold, with formula Au(OH) 3. It is also called auric acid with formula H 3 AuO 3. It is easily dehydrated above 140 °C to gold(III) oxide. Salts of auric acid are termed aurates.
