• All of the molecular molybdenum fluorides, MoF to MoF 6 , have been synthesised from the reaction of thermally evaporated molybdenum atoms with fluorine molecules and atoms, trapped in argon matrices, and characterised by matrix isolation IR spectroscopy in conjunction with DFT calculations. This includes the first spectroscopic characterisation of MoF and MoF 2 , the latter of which is very bent with a bond angle of ca. 133°, the reassignment of the IR spectral data for trigonal planar MoF 3 , the observation of tetrahedral MoF 4 , the assignment of new features to MoF 5 which displays a Jahn-Teller distorted trigonal bipyramidal structure, and octahedral MoF 6 . When the reaction of fluorine molecules and heated molybdenum is allowed to take place, MoF 6 , MoF 4 and (MoF 5 ) 3 are observed.
