only one documented case, that of PbS2 which adopts two polymorphic forms corresponding to Pb(IV)(S2−)2 and Pb(II)(S22−). Here we have taken advantage of metathetic reactions using salts of weakly coordinating anions and we have prepared for the first time Ag(I)2S2O8, silver(I) peroxydisulphate. The title compound crystallizes in the non-centrosymmetric Cc space group with partial disorder of the anionic
