Vanadium(V) fluoride, also known as vanadium pentafluoride, is a chemical compound with the formula VF₅. It is a yellow crystalline solid and is one of the most thermally stable vanadium compounds.

Structure

Vanadium(V) fluoride adopts a trigonal bipyramidal geometry in the gas phase. In the solid state, it forms a polymeric structure with bridging fluoride ligands. The V-F bond lengths are consistent with those found in other vanadium fluorides.

Synthesis

Vanadium(V) fluoride can be synthesized by the direct fluorination of vanadium metal or vanadium(IV) oxide at elevated temperatures. The reaction is highly exothermic and must be controlled to prevent decomposition of the product.

Reactions

Vanadium(V) fluoride is a strong oxidizing agent and reacts with water to form vanadium oxyfluorides and hydrofluoric acid. It also reacts with organic compounds, often leading to fluorination of the organic substrate.

Applications

While vanadium(V) fluoride is not widely used in industry, it is of interest in research settings for its unique properties and potential applications in fluorination reactions.

Safety

Vanadium(V) fluoride is highly corrosive and toxic. It should be handled with care, using appropriate protective equipment to avoid exposure.
