Osmium octafluoride is an inorganic chemical compound of osmium metal and fluorine with the chemical formula OsF
8.[3][4] Some sources consider it to be a still hypothetical compound.[5] An early report of the synthesis of OsF
8 was much later shown to be a mistaken identification of OsF
6.[6] Theoretical analysis indicates OsF
8 would have an approximately square antiprismatic molecular geometry.[7]
