Chemical compound

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.

-==Properties==
+'''Vanadium(V) fluoride''', also known as '''vanadium pentafluoride''', is a chemical compound with the formula '''VF<sub>5</sub>'''. It is a yellow crystalline solid and is one of the most thermally stable vanadium compounds.
-Vanadium pentafluoride is a volatile, colorless to pale yellow liquid at room temperature, making it distinct from the solid states of its lower fluoride counterparts. It has a strong oxidizing property and reacts violently with water, releasing oxygen and forming [[Vanadium(V) oxide|vanadium(V) oxide]] and hydrofluoric acid. Due to its high reactivity, VF5 is usually handled under strict safety protocols to prevent its decomposition and the subsequent release of toxic gases.
+==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==
-The synthesis of vanadium pentafluoride typically involves the direct fluorination of vanadium metal or vanadium(V) oxide with elemental fluorine. The reaction requires careful control of temperature and the use of corrosion-resistant equipment due to the aggressive nature of fluorine gas and the product itself.
+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==
-Vanadium pentafluoride is primarily used in research settings, particularly in the study of its potential as a catalyst in certain organic reactions. Its strong oxidizing ability can be harnessed to facilitate the breakdown of complex organic molecules, although its practical applications are limited by its reactivity and the difficulty in handling.
+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==
-Handling vanadium pentafluoride requires stringent safety measures due to its corrosive nature and the potential release of toxic gases upon decomposition. Appropriate personal protective equipment (PPE), such as gloves and goggles, and the use of fume hoods are essential when working with this compound.
+Vanadium(V) fluoride is highly corrosive and toxic. It should be handled with care, using appropriate protective equipment to avoid exposure.
