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 is prepared from the 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
