Preparation and reactions

Rhenium(VI) chloride was first generated as a mixture by chlorination of Re films.[2] Bulk samples can be prepared by combining rhenium hexafluoride with excess boron trichloride:

2 ReF6 + 6 BCl3 → ReCl6 + 6 BF2Cl

It is unstable at room temperature with respect to rhenium(V) chloride:

2 ReCl6 → [ReCl5]2 + Cl2
