Tris(4-bromophenyl)ammoniumyl hexachloroantimonate

<p>Tris(4-bromophenyl)ammoniumyl hexachloroantimonate is the <a href="/facts/Organic_compound/gqCNaN45">organic compound</a> with the formula [(4-BrC6H4)3N]SbCl6. Commonly known as magic blue, it is the <a href="/facts/Hexachloroantimonate/6hfU9lgW">hexachloroantimonate</a> salt of an amine <a href="/facts/Radical_cation/N4vFqKrV">radical cation</a>. It is a blue solid that reacts with many solvents but is soluble in <a href="/facts/Acetonitrile/fNpbvRp6">acetonitrile</a>. The compound is a popular oxidizing agent in organic and <a href="/facts/Organometallic_chemistry/bhqFz2P0">organometallic chemistry</a>, with a reduction potential of 0.67 V versus <a href="/facts/Ferrocene/jKtu9Cp8">ferrocene</a>/ferrocenium (<a href="/facts/Acetonitrile/fNpbvRp6">acetonitrile</a> solution) or 0.70 V versus <a href="/facts/Ferrocene/jKtu9Cp8">ferrocene</a>/ferrocenium (<a href="/facts/Dichloromethane/mHyeTD2D">dichloromethane</a> solution).
</p><p>The structure of the cation consists of a three-bladed propeller structure with a planar amine.
