Application

Tungsten(IV) chloride is primarily used as a precursor for the synthesis of highly conductive tungsten diselenide nanosheets, serving as a critical reactant in this process. This gray powder is sensitive to moisture and decomposes when heated. It is a black, diamagnetic solid with a polymeric structure consisting of linear chains of tungsten atoms in an octahedral geometry. The compound's structure features alternating bonding and nonbonding tungsten separations, and it typically results from the reduction of tungsten hexachloride (WCl6) using reductants like antimony, which has been shown to be particularly effective.
