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