Tellurium dioxide is also converted into the tetrachloride by the action of sulphur monochloride or even hydrogen chloride. Tellurium tetrachloride is a colourless, crystalline solid; it melts at 225° C. to a yellow liquid, the colour of which deepens as the boiling- point, 390° C., is approached.

10. Preparation of TeCl 4: In a two neck flask, equipped with a reflux condenser and a drying tube, tellurium (10.16 g, 80 mmol) was treated with sulfuryl chloride (50 mL; excess) added dropwise. The suspension was refluxed for 12 h, cooled to room temperature and the excess of sulfuryl chloride distilled to dryness, leaving a white to light-gray solid in the flask.
