The material is prepared by reduction of tungsten hexachloride. One method involves the use of tetrachloroethylene as the reductant [2] 2 WCl 6 + C 2 Cl 4 → W 2 Cl 10 + C 2 Cl 6. 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 tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
Tungsten hexachloride is readily hydrolyzed, even by moist air, giving the orange oxychlorides WOCl 4 and WO 2 Cl 2, and subsequently, tungsten trioxide. WCl 6 is soluble in carbon disulfide, carbon tetrachloride, and phosphorus oxychloride. [2] Methylation with trimethylaluminium affords hexamethyl tungsten: WCl 6 + 3 Al 2 (CH 3) 6 → W(CH 3 ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Tungsten(II) chloride is the inorganic compound with the formula W 6 Cl 12. It is a polymeric cluster compound. The material dissolves in concentrated hydrochloric acid, forming (H 3 O) 2 [W 6 Cl 14](H 2 O) x. Heating this salt gives yellow-brown W 6 Cl 12. [1] The structural chemistry resembles that observed for molybdenum(II) chloride.
Tungsten(VI) oxide is soluble in aqueous base, forming tungstate (WO 4 2−). This oxyanion condenses at lower pH values, forming polyoxotungstates. [62] The broad range of oxidation states of tungsten is reflected in its various chlorides: [61] Tungsten(II) chloride, which exists as the hexamer W 6 Cl 12
Tungsten dichloride dioxide, or Tungstyl chloride is the chemical compound with the formula W O 2 Cl 2. It is a yellow-colored solid. It is used as a precursor to other tungsten compounds. Like other tungsten halides, WO 2 Cl 2 is sensitive to moisture, undergoing hydrolysis.
