|Section2= |Section8= }} Silver subfluoride is the inorganic compound with the formula Ag2F. This is an unusual example of a compound where the oxidation state of silver is fractional. The compound is produced by the reaction of silver and silver(I) fluoride:〔Lee Poyer, Maurice Fielder, Hugh Harrison, Burl E. Bryant "Disilver Fluoride: (Silver “Subfluoride”)" Inorganic Syntheses, 1957, Volume 5, 92–94. 〕 :Ag + AgF → Ag2F It forms small crystals with a bronze reflex and is a good conductor of electricity. On contact with water almost instant hydrolysis occurs with the precipitation of silver (Ag) powder. == Crystal structure == Ag2F adopts the anti-CdI2 crystal structure, i.e. the same structure as cadmium iodide, CdI2, but with "Ag½+ " centres in the I− positions and F− in the Cd2+ positions. The shortest distance between silver atoms is 299.6 pm (compared to 289 pm in the metal).〔Egon Wiberg, Arnold Frederick Holleman (2001) ''Inorganic Chemistry'', Elsevier ISBN 0-12-352651-5〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Silver subfluoride」の詳細全文を読む スポンサード リンク
