Appearance blue-green solid
Melting point 70 °C (158 °F; 343 K)
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Osmium pentafluoride is an inorganic compound with the formula OsF5. It is a blue-green solid. Like the pentafluorides of Ru, Rh, and Ir, OsF5 exists as a tetramer in the solid state.

Preparation

Osmium pentafluoride can be prepared by reduction of osmium hexafluoride with iodine as a solution in iodine pentafluoride:[1]

10 OsF6 + I2 → 10 OsF5 + 2 IF5
