Abstract

An adduct of two SO2 molecules and one dithionate ion, namely the anion of the title compound 1 (see below, right-hand side), can be obtained from bis(η6-benzene)chromium and SO2 in acetonitrile. The SO2 molecules are coupled to the dithionate ion via unusually long S(SO2)-O(S2O6) bonds (243 pm).
