Vanadocene dichloride is an organometallic complex with formula (η⁵-C₅H₅)₂VCl₂ (commonly abbreviated as Cp₂VCl₂). It is a structural analogue of titanocene dichloride but with vanadium(IV) instead of titanium(IV). This compound has one unpaired electron, hence Cp₂VCl₂ is paramagnetic. Vanadocene dichloride is a suitable precursor for variety of bis(cyclopentadienyl)vanadium(IV) compounds.
