Rhenium pentachloride

Rhenium pentachloride is an inorganic compound with the formula Re2Cl10.

[4] Rhenium pentachloride has a bioctahedral structure and can be described as Cl4Re(μ-Cl)2ReCl4.

The preparation involves chlorination of rhenium at temperatures up to 900 °C.

[8] Although rhenium pentachloride has no commercial applications, it is of historic significance as one of the early catalysts for olefin metathesis.

Oxygenation affords the Re(VII) oxychloride:[10] Comproportionation of the penta- and trichloride gives rhenium tetrachloride.

NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability (red): no hazard code Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazard W: Reacts with water in an unusual or dangerous manner. E.g. sodium, sulfuric acid
