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.
Reduction of WCl 6 can be effected with a mixture of tetrachloroethylene and tetraphenylarsonium chloride: [5] 2 WCl 6 + Cl 2 C=CCl 2 + 2 (C 6 H 5) 4 AsCl → 2 (C 6 H 5) 4 As[WCl 6] + Cl 3 C−CCl 3. The W(V) hexachloride is a derivative of tungsten(V) chloride. It reacts with arsenic or hydrogen arsenide to form tungsten arsenide. [6] [7]
Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula W F 6. It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m 3 (22 lb/cu yd) (roughly 11 times heavier than air). [2] [3] It is the densest known gas under standard ambient temperature and pressure (298 K, 1 atm). [4]
Tungsten(VI) oxytetrachloride is the inorganic compound with the formula W O Cl 4. This diamagnetic solid is used to prepare other complexes of tungsten. The red crystalline compound is soluble in nonpolar solvents but it reacts with alcohols and water and forms adducts with Lewis bases.
Tungsten(III) chloride is the inorganic compound with the formula W 6 Cl 18. It is a cluster compound. It is a brown solid, obtainable by chlorination of tungsten(II) chloride. [2] Featuring twelve doubly bridging chloride ligands, the cluster adopts a structure related to the corresponding chlorides of niobium and tantalum.
