|Section2= |Section3= |Section7= |Section8= }} Rhenium pentachloride is an inorganic compound of chlorine and rhenium. The compound has the formula Re2Cl10 but it is usually referred to as the pentachloride. It is a red-brown solid. It is the highest chloride of rhenium. ==Structure and preparation== Rhenium pentachloride has a bioctahedral structure and can be formulated as Cl4Re(μ-Cl)2ReCl4. The Re-Re distance is 3.74 Å. The motif is similar to that seen for tantalum pentachloride. This compound was first prepared in 1933, a few years after the discovery of rhenium. The preparation involves chlorination of rhenium at temperatures up to 900 °C.〔Roger Lincoln, Geoffrey Wilkinson "Rhenium Pentachloride and Volatile Metal Chlorides by Direct Chlorination Using a Vertical-Tube Reactor" Inorganic Syntheses, 1980, Volume 20, Pages 41–43. .〕 The material can be purified by sublimation. Being formed by burning Re metal in chlorine, ReCl5 is the most oxidized binary chloride of Re. With a d2 configuration, ReCl5 could conceivably be further chlorinated. Rhenium hexachloride (ReCl6) is uncertain, but rhenium hexafluoride and rhenium heptafluoride are known.〔Stuart A. Macgregor and Klaus H.
