This white solid forms a monohydrate and is mildly deliquescent.
It is a useful source of the Ag+ ion, although the presence of perchlorate presents risks.
Silver perchlorate is noteworthy for its solubility in aromatic solvents such as benzene (52.8 g/L) and toluene (1010 g/L).
[1] In these solvents, the silver cation binds to the arene, as has been demonstrated by X-ray crystallographic studies on crystals obtained from such solutions.
X-ray diffraction experiments show that aqueous solutions contain [Ag(H2O)2]+ with Ag-O distances near 240 picometer.
