Vanadium Hexacarbonyl[edit]
6.png)
Vanadium hexacarbonyl, with the chemical formula V(CO)6, is a metal carbonyl compound consisting of a vanadium atom surrounded by six carbon monoxide ligands. It is a member of the transition metal carbonyls, which are complexes formed between transition metals and carbon monoxide.
Structure and Bonding[edit]
Vanadium hexacarbonyl is an octahedral complex, where the vanadium atom is at the center of an octahedron formed by six carbon monoxide ligands. The V-C bond is a result of both _-donation from the carbon monoxide to the vanadium and π-backbonding from the vanadium to the carbon monoxide. This dual bonding interaction stabilizes the complex.
Synthesis[edit]
Vanadium hexacarbonyl can be synthesized by the reaction of vanadium pentachloride (VCl5) with carbon monoxide under high pressure. The reaction typically requires a reducing agent, such as sodium or magnesium, to facilitate the reduction of vanadium from the +5 oxidation state to the zero oxidation state in the complex.
Properties[edit]
Vanadium hexacarbonyl is a volatile, air-sensitive compound that decomposes upon exposure to air. It is typically handled under an inert atmosphere, such as nitrogen or argon, to prevent decomposition. The compound is soluble in nonpolar organic solvents, such as hexane and toluene.
Applications[edit]
While vanadium hexacarbonyl itself is not widely used in industry, it serves as a precursor to other vanadium compounds and as a reagent in organometallic chemistry. It is also of interest in academic research for studying the bonding and electronic properties of metal carbonyls.
Safety[edit]
Vanadium hexacarbonyl is considered toxic and should be handled with care. It can release carbon monoxide, a toxic gas, upon decomposition. Proper ventilation and protective equipment are necessary when working with this compound.
