Vanadium tetrafluoride

Vanadium tetrafluoride, VF4. Green solid prepared HF on VCI4. Forms hexa-fluorovanadate(IV) ion (VFa) ". VOF2 formed by hydrolysis. [Pg.417]

Vanadium Tetrafluoride, hypovanadic fluoride, VF4, is produced by the action of anhydrous hydrogen fluoride on the corresponding chlorine compound, VC14, at temperatures from —28° to 0° C. It is an extremely deliquescent brown powder which readily undergoes hydrolysis with water, so that it does not give rise to double salts as in the case of the trifluoride. Its density at 23° C. is 2 9749. It decomposes above 325° C., yielding a mixture of the pentafluoride and the trifluoride 1... [Pg.38]

Fluorides Vanadium trifluonde VPs, green crystalline solid vanadium tetrafluoride VF4, brownish-yellow crystalline solid vanadium pentafluo-ride VF5, brownish-yellow crystalline solid, sublimes on heating. [Pg.1667]

Although the linking through fluorine bridges is different from that in palladium tetrafluoride, the fluorine atom positions in vanadium tetrafluoride correspond approximately to a hexagonal close-packed array. The linking of octahedra leads to a complex layer structure, rather than the three-dimensional lattice of the palladium tetrafluoride arrangement. [Pg.100]

Vanadium Tetrafluoride. VF4 is formed along with VF5 and VF3 in the fluorination of metallic vanadium and the difference in volatilities of the three fluorides allows their separation by fractional sublimation. It can also be prepared by treatment of VCI4 with anhydrous HF in an inert solvent such as CCI3F at -78 °C. Pure VF4 is a bright green hygroscopic solid, which disproportionates at 100 °C to VF5 and VF3. Its structure consists of octahedrally coordinated VFg units linked... [Pg.5024]

The double fluoride, ammonium hexafluorovanadate ((NH4)3VF6), forms from the oxide at 210 to 250 °C, but decomposes at 600 to 700 °C to yield pure vanadium fluoride. Examples of metal fluorides obtainable through the double fluoride route include uranium tetrafluoride, beryllium difluoride and the rare earth fluorides ... [Pg.414]
