Rhenium(VI) chloride is the inorganic compound with the formula ReCl6. It is a black paramagnetic solid. The molecules adopt an octahedral structure as seen in tungsten(VI) chloride.[1]

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
