文摘

When exposed to air at ambient conditions, AgSO₄ slowly reacts with moisture, yielding AgSO₄⋅H₂O. 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.
