Vanadium(IV) fluoride (VF₄) 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 Tetrafluoride", Becker S., Muller B. G., Angew. Chem. Intnl. Ed. Engl. 29 (1990) No. 4 406]
