Tungsten(IV) chloride is an inorganic compound with the formula WCl4.
The compound is of interest in research as one of a handful of binary tungsten chlorides.
Many reductants have been reported, including red phosphorus, tungsten hexacarbonyl, gallium, tin, and antimony.
It consists of linear chains of tungsten atoms each in octahedral geometry.
Reduction of tungsten(IV) chloride with sodium yields the ditungsten(III) heptachloride derivative:[2]
