Preparation and reactions
Molybdenum(VI) chloride is prepared from the molybdenum hexafluoride with excess boron trichloride:
- MoF6 + 3 BCl3 → MoCl6 + 3 BF2Cl
It is unstable at room temperature with respect to molybdenum(V) chloride and chlorine and decomposition completes within several days:
- 2 MoCl6 → [MoCl5]2 + Cl2
