Molybdenum(V) fluoride
Molybdenum fluoride is an inorganic compound with the formula MoF5. It is a hygroscopic yellow solid. Like most pentafluorides, it exists as a tetramer.
Production
Molybdenum fluoride is produced by the reaction of molybdenum and molybdenum hexafluoride: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.
About 165 °C, it disproportionates to the tetra- and hexafluoride:
