Preparation

Tellurium dichloride can be produced by react tellurium with difluorodichloromethane.[2][3]

It can also produced by the reaction of tellurium and tellurium tetrachloride.[4]

Properties

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]

Reactions

Tellurium dichloride reacts with barium chloride in water to form barium tellurite.[6]
