Potassium hexachlororhenate, also known as potassium chlororhenite, is an inorganic chemical compound with the formula K2ReCl6. It is a light-green crystalline solid soluble in hydrochloric acid.
Production and reactions
Potassium hexachlororhenate is most commonly prepared by the reduction of potassium perrhenate with potassium iodide, hypophosphorous acid, or chromium(II) chloride in the presence of hydrochloric acid.[4][5][6]
It reacts with
rhenium(III) chloride.[7]
In water, it hydrolyses to form rhenium(IV) oxide.[1]
