Cyclopentadienylvanadium tetracarbonyl is the organovanadium compound with the formula (C5H5)V(CO)4. An orange, diamagnetic solid, it is the principal cyclopentadienyl carbonyl of vanadium. It can be prepared by heating a solution of vanadocene under high pressure of carbon monoxide. [1] As confirmed by X-ray crystallography, the coordination sphere of vanadium consists of η5-cyclopentadienyl and four carbonyl ligands. The molecule is a four-legged piano stool complex. [2] The compound is soluble in common organic solvents. The compound has no commercial applications.
Reduction of cyclopentadienylvanadium tetracarbonylwith sodium amalgam gives the tricarbonyl dianion:
Protonation of this salt gives Cp2V2(CO)5. [3]
Heating a mixture of cycloheptatriene and cyclopentadienylvanadium tetracarbonyl gives (cycloheptatrienyl)(cyclopentadienyl)vanadium ("trovacene"). [4]
