[{"from": "human", "value": "Use the given information to create a molecule that fulfills the desired purpose. The molecule is a chloride of vanadium. Vanadocene dichloride, dichloro bis(\u2018\u20215-cyclopentadienyl)vanadium(IV) is (\u2018\u20215-C5H5)2VCl2 (commonly abbreviated as Cp2VCl2). It is a structural analoque of titanocene dichloride but with vanadium(IV) instead of titanium(IV). Vanadium is a transition metal with the chemical symbol V and atomic number 23. The element usually combines with other elements such as oxygen, sodium, sulfur, or chloride, and occurs naturally in about 65 different minerals and in fossil fuel deposits. Vanadium is found in many organisms, and is used by some life forms as an active center of enzymes.
