Description and Uses

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 ? .

A precursor to tungsten based carbenes.
