Ag2+ is a powerful oxidizer capable of oxidizing even O
2 in certain conditions. This cation has previously been thought to be incompatible with water, and the synthesis of Ag
2+ compounds has previously been conducted in anhydrous environments. However, water molecules may in fact be attached to the voracious Ag
2+ cation without decomposition, as shown by the formation and properties of the complex salt [Ag(OH
2)
2][Ag(SO
4)
2]. More information can be found in the Full Paper by P.
