N verify (what is YN ?)

The material is prepared by reduction of tungsten hexachloride. One method involves the use of tetrachloroethylene as the reductant[2]

2 WCl6 + C2Cl4 → W2Cl10 + C2Cl6

The blue green solid is volatile under vacuum and slightly soluble in nonpolar solvents. The compound is oxophilic and is highly reactive toward Lewis bases.

Structure

The compound exists as a dimer, with a pair of octahedral tungsten(V) centres bridged by two chloride ligands. The W---W separation is 3.814 Å, which is non-bonding. The compound is isostructural with Nb2Cl10 and Mo2Cl10. The compound evaporates to give trigonal bipyramidal WCl5 monomers.[3]
