Silver subfluoride, Ag2F

When a saturated solution of silver fluoride is heated with finely divided silver, a golden-yellow, crystalline precipitate of the composition Silver subfluoride, Ag2F is produced. The reaction is attended by the evolution of 0.7 Cal., and the heat of formation of the subfluoride from its elements is 26.3 Cal. At 180° C. water-vapour converts the fluoride into the suboxide, Ag4O.

The dihydrate, Ag2F,2H2O, is obtained in colourless octahedra by evaporating a solution of silver fluoride in absence of light, and removing excess of silver fluoride by extracting with alcohol.
