Vanadocene dichloride, dichloro bis(
η5-
cyclopentadienyl)
vanadium(IV) is (η
5-C
5H
5)
2VCl
2 (commonly abbreviated as Cp
2VCl
2). It is a structural analoque of
titanocene dichloride but with vanadium(IV) instead of titanium(IV). This compound has one unpaired
electron, hence Cp
2VCl
2 is
paramagnetic. Vanadocene dichloride is a suitable precursor for variety of bis(cyclopentadienyl)vanadium(IV) compounds.
