Disilver fluoride.
Ag
2F; mol wt 234.73.
Ag 91.91%, F 8.09%.
Description and references
Prepd by electrolytic reduction of argentous
fluoride, AgF: Hettich, Z. Anorg. Allg. Chem. 167, 67 (1927); Scholder, Traulsen, ibid. 197, 57 (1931). By the reaction of
elemental silver with argentous fluoride at 50-90°: Güntz, Compt. Rend. 110, 1337 (1890); 112, 861 (1891); Poyer et al., Inorg. Synth. 5, 18 (1957).
Properties
Hexagonal, bronze-colored crystals with green
luster, d 8.57. Turns
grayish-black on prolonged exposure to air. Thermal decompn to Ag
and AgF begins at 100° and is complete at 200°. Good electrical conductor.
On contact with water almost instant hydrolysis with precipitation
of Ag powder. Apparently stable to abs ethanol; insensitive to light.
When dry may be kept in a stoppered container for weeks without evidence
of decompn.Status
