Tungsten(V) chloride is an inorganic compound with the formula W2Cl10. This compound is analogous in many ways to the more familiar molybdenum pentachloride.
The material is prepared by reduction of tungsten hexachloride. One method involves the use of tetrachloroethylene as the reductant:[1]
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.
The compound exists as a dimer, with a pair of octahedral tungsten(V) centres bridged by two chloride ligands.
