Higher sulfur oxides
Higher chemical compounds with the formula SO3+x where x lies between 0 and 1. They contain peroxo (O−O) groups, and the oxidation state of sulfur is +6 as in SO3.
Monomeric SO4 can be isolated at low temperatures (below 78 K) following the reaction of SO3 and atomic oxygen or photolysis of SO3–ozone mixtures. The favoured structure is:
Colourless polymeric condensates are formed in the reaction of gaseous
non-stoichiometric
