Tellurium dichloride is a chloride of tellurium with the chemical formula TeCl2.
Tellurium dichloride can be produced by reacting tellurium with difluorodichloromethane. [2] [3]
It can also be produced by the comproportionation of tellurium and tellurium tetrachloride. [4]
Tellurium dichloride is a black solid that reacts with water. It will melt into a black liquid and vapourize into a purple gas. [1] [5] The gas consists of monomeric TeCl2 molecules with Te–Cl bond lengths of 2.329 Å and a Cl–Te–Cl bond angle of 97.0°. [5]
Tellurium dichloride reacts with barium chloride in water to form barium tellurite.
