Vanadium(IV) fluoride
Encyclopedia
Vanadium fluoride (V
F4
) is a chemical compound
of vanadium
and fluorine
. VF4 can be prepared by reacting VCl4 with HF in CCl3F at 25 °C. VF4 decomposes at approximately 150°C to form VF3.
The structure of VF4 is related to that of SnF4 and has corner sharing VF6 octahedra. It is paramagnetic.
Vanadium
Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery gray, ductile and malleable transition metal. The formation of an oxide layer stabilizes the metal against oxidation. The element is found only in chemically combined form in nature...
