Osmium heptafluoride is an
inorganic chemical compound of osmium metal and fluorine with the chemical formula OsF
7.[2][3] It was first reported in 1966 by the reaction of fluorine and osmium at 600 °C and 400 atm,[4] but later experiments can’t reproduce this compound.[5]

Physical properties
Osmium(VII) fluoride forms a bluish-yellow hygroscopic substance, extremely unstable.[6] The compound starts decomposing at –100 °C. It should be stored in a nickel vessel at the temperature of liquid nitrogen.
Chemical properties
Osmium heptafluoride decomposes to osmium hexafluoride when slightly heated:
- 2OsF7 → 2OsF6 + F2
