[Chemical Properties]

dark grey-violet crystalline powder
[Uses]

A precursor to tungsten based carbenes.
[Uses]

Precursor to tungsten-based carbenes which catalyze the olefin metathesis reactions of 1- and 2-octene.
[Description]

Tungsten(VI) chloride, WCl6, is a dark violet blue species that exists as a volatile solid under standard conditions. It is an important starting reagent in the preparation of tungsten compounds. As a d0 ion, W(VI) forms diamagnetic derivatives. WCl6 is octahedral with equivalent W-Cl distances of 2.24-2.26 ? .
[Definition]

ChEBI: Tungsten hexachloride is a tungsten coordination entity.
[Preparation]

WCl6 can be prepared by chlorinating tungsten metal in a sealed tube at 600℃.
W +3Cl2→WCl6
[Reactions]

The tungsten reagents were prepared from tungsten hexachloride (Tungsten(VI) Chloride) in three ways: (i) with butyllithium; (ii) with a lithium dispersion; and (iii) with lithium iodide. In each case the ratio of WCl6 to lithium reagent is important. TUNGSTEN(VI) CHLORIDE
[Purification Methods]

Sublime it in a stream of Cl2 in a high temperature furnace and collect it in a receiver cooled in a Dry Ice-acetone bath in an inert atmosphere because it is sensitive to moisture. It is soluble in CS2, CCl4, CHCl3, POCl3, *C6H6, pet ether and Me2CO. Its solutions decompose on standing. Good crystals can be obtained by heating WCl6 in CCl4 to 100o in a sealed tube, followed by slow cooling (tablets of four-sided prisms). Store it in a desiccator over H2SO4 in the dark.
