Tungsten hexachloride is an inorganic chemical compound of tungsten and chlorine with the chemical formula WCl6. This dark violet blue compound exists as volatile crystals under standard conditions. It is an important starting reagent in the preparation of tungsten compounds.[1] Other examples of charge-neutral hexachlorides are rhenium(VI) chloride and molybdenum(VI) chloride. The highly volatile tungsten hexafluoride is also known.

As a d0 atom, tungsten hexachloride is diamagnetic.
