Synthesis
editReaction of diiodosyl sulfate and sulfur trioxide:[2][3][4]
- (IO)2SO4 + 2 SO3 → I2(SO4)3
Iodine sulfate is also produced when elemental I2 , I2O5 and SO3 react.[5]
Physical properties
editIodine sulfate forms light yellow hygroscopic crystals.[2][3][6]
Chemical properties
editIodine sulfate is soluble in organic liquids[3] and stable in anhydrous and strongly acidic solvents.[6] In a humid environment, it darkens due to decomposition that releases molecular iodine.[2]

According to the equation: (IO)2SO4 + 2SO3 = I2(SO4)3 ... the yellow crystals could be isolated. They showed properties typical of a neutral iodine salt, being specially sensitive to moisture. [Fichter et al.] showed that the compound was mainly neutral iodine sulphate I2(SO4)3 ... the neutral salts have a much lighter yellow colour[,] a greater solubility in organic liquids and a greater sensitivity to water.
