Chemical compound

Tungsten(II) chloride is theinorganic compound with the formula W₆Cl₁₂. It is apolymeric cluster compound. The material dissolves in concentratedhydrochloric acid, forming (H₃O)₂[W₆Cl₁₄](H₂O)_x. Heating this salt gives yellow-brown W₆Cl₁₂.^[1] The structural chemistry resembles that observed formolybdenum(II) chloride.

Tungsten(II) chloride is prepared by reduction of the hexachloride. Bismuth is a typical reductant:

6 WCl₆ + 8 Bi → W₆Cl₁₂ + 8 BiCl₃
