Rhenium(VI) chloride
Rhenium 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 chloride.
Preparation and reactions
Rhenium chloride was first generated as a mixture by chlorination of Re films. Bulk samples can be prepared by combining rhenium hexafluoride with excess boron trichloride:It is unstable at room temperature with respect to rhenium(V) chloride:
