Abstract: 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 ⁵-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.
