Molecular Formula: AgClO4

Molecular Weight: 207.32

Percent Composition: Ag 52.03%, Cl 17.10%, O 30.87%

Literature References: Prepn from NOClO4 + AgBr: Markowitz et al., J. Inorg. Nucl. Chem. 16, 159 (1960).

Properties: Deliquescent crystals, dec 486°. d25 2.806. Freely sol in water: 557 g/l00 ml; a satd aq soln contains 84.8% w/w at 25°: Smith, Ring, J. Am. Chem. Soc. 59, 1889 (1937). Much less sol in 60% perchloric acid (5.63% w/w). Forms a monohydrate stable to 43°. Sol in many organic solvents, e.g., aniline, pyridine, benzene, toluene, nitromethane, glycerol, nitrobenzene, and chlorobenzene. Solvated crystals have been obtained contg 6 mols aniline, 4 mols pyridine, 1 mol benzene, 1 mol toluene. These compds explode readily when struck: Brinkley, J. Am. Chem. Soc. 62, 3524 (1940).
