Tris(4-bromophenyl)ammoniumyl hexachloroantimonate is the organic compound with the formula [(4-BrC6H4)3N]SbCl6. Commonly known as magic blue, it is the hexachloroantimonate salt of an amine radical cation. It is a blue solid that reacts with many solvents but is soluble in acetonitrile. The compound is a popular oxidizing agent in organic and organometallic chemistry, with a reduction potential of 0.7 V vs. ferrocene/ferrocenium (MeCN solution).[1]
The structure of the cation consists of a three-bladed propeller structure with a planar amine. It is nearly identical to the parent triphenylamine. The weakly coordinating anion is SbCl6-, which is octahedral.[2]
