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
