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 t
he synt
hesis of Ag
2+ compounds has previously been conducted in anhydrous environments. However, water molecules may in fact be attac
hed to t
he voracious Ag
2+ cation without decomposition, as shown by t
he formation and properties of t
he complex salt [Ag(OH
2)
2][Ag(SO
