Neither sulfate nor peroxodisulfate. Thermal decomposition of transition‐metal sulfates, such as CuSO 4 , usually occurs by desulfation (elimination of SO 3 ). In their Communication on page 10524 ff. , W. Grochala et al. show that Ag II SO 4 exhibits an unusual reductive pathway of thermal decomposition, which is connected with low‐temperature elimination of O 2 and formation of the disulfate of Ag I . Although the decomposition pathway renders Ag I 2 S 2 O 7 , similar to K 2 S 2 O 8 (with its peroxo OO bridge), the thermodynamics and kinetics of this reaction differ markedly for both compounds.
