    Vanadium(V) chloride is the inorganic compound with the formula VCl5. It is a black diamagnetic solid. The molecules adopt a bioctahedral structure similar to that of niobium(V) chloride.[1]

    Preparation and reactions

    [edit]

    Vanadium(V) chloride is prepared from the vanadium pentafluoride with excess boron trichloride:

    2 VF5 + 10 BCl3 → [VCl5]2 + 10 BF2Cl

    It is unstable at room temperature with respect to vanadium(IV) chloride:

    [VCl5]2 → 2 VCl4 + Cl2

    In contrast, the heavier analogues NbCl5 and TaCl5 are stable and not particularly oxidizing.
