Polyoxoacids with S_O_S units
Although K salts of the polysulfuric acids HO3S(OSO2)nOSO3H (n = 2, 3, 5, 6) have been obtained by the reaction of SO3 with K2SO4, the free acids cannot be isolated. Disulfuric and trisulfuric acids are present in oleum, i.e. when SO3 is dissolved in concentrated H2SO4. The salt [NO2]2[S3O10] has also been prepared and structurally characterized. Structure 1.1 shows [S3O10]2- as a representative of this group of polyoxoanions.
