Acetonitrile­chloro­tris(η⁵-cyclo­penta­dienyl)vanadium(IV) tetrachloroferrate(III)

The structure of the title compound, [V(C₅H₅)₂Cl(C₂H₃N)][FeCl₄], a potential spermicidally active species, has been determined. This compound has a typical bent metallocene structure, in which two η⁵-bonded cyclo­penta­dienyl rings, an N-coordinated acetonitrile molecule and a Cl ligand occupy tetrahedral positions around the V^IV atom. The V—N bond length was found to be 2.087 (2) Å.
