Characteristic
Vanadium(IV) fluoride (VF4) is an inorganic compound of vanadium and fluorine. It is paramagnetic yellow-brown solid that is very hygroscopic. Unlike the corresponding vanadium tetrachloride, the tetrafluoride is not volatile because it adopts a polymeric structure. It decomposes before melting.
Chemical formula：VF4
Molar mass：126.9351 g·mol−1
Appearance：Lime green powder, hygroscopic
Odor：Odorless
Density：3.15 g/cm3 (20 °C)
2.975 g/cm3 (23 °C)
Melting point：325 °C (617 °F; 598 K) at 760 mmHg decomposes
Boiling point：Sublimes
Solubility in water：Very soluble
Solubility：Soluble in acetone, acetic acid
Very slightly soluble in SO2Cl2, alcohols, CHCl3
Crystal structure：Monoclinic, mP10
Application
Used as a fluoridation agent.
