Tellurium dichloride is a chloride of tellurium with the chemical formula TeCl2.
Preparation
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]
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] 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]
Reactions
Tellurium dichloride reacts with barium chloride in water to form barium tellurite.
