Gold(III) chloride Wikipedia

OverviewStructurePreparationReactionsApplications in organic synthesis

Gold(III) chloride, traditionally called auric chloride, is a chemical compound of gold and chlorine. With the molecular formula Au2Cl6, the name gold trichloride is a simplification, referring to the empirical formula, AuCl3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold compounds. There is also another related chloride of gold, gold(I) chloride (AuCl). Chloroauric acid, HAuCl4, the product formed when gold dissolves in aqua regia, is sometimes referred

Gold(III) chloride

StructureChemical PropertiesPreparationUsesPrecautionsAuCl3 exists as a dimer both as a solid and as a vapour; the bromide AuBr3 follows the same pattern. Each Au centre is square planar. This structure is reminiscent of the bi tetrahedral structures adopted by AlCl3 and FeCl3. The bonding in AuCl3 is mainly covalent, reflecting the high oxidation state and relatively high electronegativity (for a metal) of the gold.
