Tetrabromoauric acid is an inorganic compound with the formula . It is the bromide analog of
chloroauric acid
Chloroauric acid is an inorganic compound with the chemical formula . It forms hydrates . Both the trihydrate and tetrahydrate are known. Both are orange-yellow solids consisting of the planar anion. Often chloroauric acid is handled as a soluti ...
. It is generated analogously, by reacting a mixture of
hydrobromic and
nitric acid
Nitric acid is the inorganic compound with the formula . It is a highly corrosive mineral acid. The compound is colorless, but older samples tend to be yellow cast due to decomposition into oxides of nitrogen. Most commercially available nitri ...
s with elemental gold.
The oxidation state of gold in and anion is +3. The salts of (tetrabromoauric(III) acid) are tetrabromoaurates(III), containing anions (tetrabromoaurate(III) anions), which have
square planar molecular geometry
The square planar molecular geometry in chemistry describes the stereochemistry (spatial arrangement of atoms) that is adopted by certain chemical compounds. As the name suggests, molecules of this geometry have their atoms positioned at the corn ...
