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.
Tungsten(II) chloride, which exists as the hexamer W 6 Cl 12; Tungsten(III) chloride, which exists as the hexamer W 6 Cl 18; Tungsten(IV) chloride, WCl 4, a black solid, which adopts a polymeric structure. Tungsten(V) chloride WCl 5, a black solid which adopts a dimeric structure. Tungsten(VI) chloride WCl 6, which contrasts with the ...
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 chloride can refer to: Tungsten(II) chloride, WCl 2; Tungsten(III) chloride, WCl 3; Tungsten(IV) chloride, WCl 4; Tungsten(V) chloride, WCl 5; Tungsten(VI ...
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.
The solidus is the locus of temperatures (a curve on a phase diagram) below which a given substance is completely solid (crystallized). The solidus temperature specifies the temperature below which a material is completely solid, [ 2 ] and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium .
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.
