Molybdenum difluoride dioxide is the inorganic compound with the formula MoF2O2. It is a white, diamagnetic, volatile solid.




Structure



Gaseous molybdenum difluoride dioxide is a tetrahedral molecule. According to X-ray crystallography, the solid is a coordination polymer consisting of trigonal primatic chains of made by linking Mo3F6O6 monomers. The fluoride and oxide positions are disordered. A similar motif is adopted by titanium tetrafluoride.




Synthesis and reactions


The compound can be obtained by thermal decomposition of the dioxotetrafluoride, which in turn is obtained from sodium molybdate:

Na2MoO4 + 4 HF → Na2MoF4O2 + 2 H2O
Heating sodium dioxotetrafluoride to 400 °C gives monomeric difluoride dioxide, which polymerizes upon condensation:

Na2MoF4O2 → 2 NaF + MoF2O2
The compound also arises by hydrolysis of molybdenum oxytetrafluoride:

MoF4O + H2O → 2 HF + MoF2O2
The compound dissolves in dimethylformamide to give a bis(adduct):

MoF2O2 + 2 OC(H)N(CH3)2 → MoF2O2(OC(H)N(CH3)2)2
