Abstract

When exposed to air at ambient conditions, AgSO₄ slowly reacts with moisture, yielding AgSO₄ ⋅H₂ O. The crystal structure determination (powder data) shows that it may be described as [Ag(OH₂ )₂ ][Ag(SO₄ )₂ ], with some sulfate groups being shared between different Ag²⁺ cations, resembling in that way its Cu²⁺ analogue. [Ag(OH₂ )₂ ][Ag(SO₄ )₂ ], the first hydrate of a compound of Ag²⁺ , was extensively characterized using many physicochemical methods.
