[3] In the solid state, it is a tetrameric cubane-type cluster, consisting of a Te4Cl4 core and three terminal chloride ligands for each Te.

[1] Yet another method involves the reaction of tellurium with sulfur monochloride (S2Cl2) at room temperature.

This exothermic reaction rapidly forms white needle-like crystals of TeCl4.

Its equivalent weight is high, and the toxicity of organotellurium compounds is problematic.

[7] It adds to alkenes to give Cl-C-C-TeCl3 derivatives, wherein the Te can be subsequently removed with sodium sulfide.
