Neither sulfate nor peroxodisulfate. Thermal decomposition of transition-metal sulfates, such as CuSO4, usually occurs by desulfation (elimination of SO3). In their Communication on page 10524 ff., W. Grochala et al. show that AgIISO4 exhibits an unusual reductive pathway of thermal decomposition, which is connected with low-temperature elimination of O2 and formation of the disulfate of AgI. Although the decomposition pathway renders AgI2S2O7, similar to K2S2O8 (with its peroxo OO bridge), the thermodynamics and kinetics of this reaction differ markedly for both compounds.
