Vanadium(III) fluoride is the chemical compound with the formula VF3. This gray-green, refractory solid is obtained in a two-step procedure from V2O3. [Sturm, B. J.; Sheridan, C. W. "Vanadium(III) Fluoride" Inorganic Syntheses 1963; Vol. 7, pages 52-54. ISBN 0-88275-165-4.] The first step entails conversion to the hexafluorovanadate(III) salt using ammonium bifluoride:

:V2O3 + 6 (NH4)HF2 → 2 (NH4)3VF6 + 3 H2O

In the second step, the hexafluorovanadate is thermally decomposed.:(NH4)3VF6 → 3 NH3 + 3 HF + VF3

The thermal decomposition of ammonium salts is a relatively common method for the preparation of inorganic solids.

VF3 can also be prepared by treatment of V2O3 with HF.VF3 is a crystalline solid with 6 coordinate vanadium atoms with bridging fluorine atoms. The magnetic moment indicates the presence of 2 unpaired electons.
