Molybdenum oxytetrafluoride is the inorganic compound with the formula MoOF4. It is a white, diamagnetic solid. According to X-ray crystallography, it is a coordination polymer consisting of a linear chain of alternating Mo and F atoms. Each Mo center is octahedral, the coordination sphere being defined by oxide, three terminal fluorides, and two bridging fluorides.[1] In contrast to this motif, tungsten oxytetrafluoride crystallizes as a tetramer, again with bridging fluoride ligands.[2]
Reactions
The acetonitrile adduct of molybdenum oxytetrafluoride can be prepared by treating molybdenum hexafluoride with hexamethyldisiloxane in acetonitrile:[3]
- MoF6 + [(CH3)3Si]2O + CH3CN → MoOF4(NCCH3) + 2 (CH3)3SiF
Molybdenum oxytetrafluoride is susceptible to hydrolysis to give molybdenum difluoride dioxide.
