Infobox references

Molybdenum(V) fluoride is an inorganic compound with the formula MoF5. It is a hygroscopic yellow solid. Like most pentafluorides, it exists as a tetramer.[2]

## Production

Molybdenum(V) fluoride is produced by the reaction of molybdenum and molybdenum hexafluoride:[3]

Mo + 5 MoF6 → 6 MoF5

About 165 °C, it disproportionates to the tetra- and hexafluoride:[1]

2 MoF5 → MoF4 \+ MoF6
