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

It can also be prepared by the reduction of molybdenum hexafluoride with phosphorus trifluoride or tungsten hexacarbonyl, or by the oxidation of elemental molybdenum with fluorine at 900 °C.^[3]

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

2 MoF₅ → MoF₄ + MoF₆
