It is a colorless, highly toxic gas with an unpleasant odor.

[citation needed] Tellurium hexafluoride is a highly symmetric octahedral molecule.

Its physical properties resemble those of the hexafluorides of sulfur and selenium.

At temperatures below −38 °C, tellurium hexafluoride condenses to a volatile white solid.

[6] For example, TeF6 slowly hydrolyzes to Te(OH)6: Treatment of tellurium hexafluoride with tetramethylammonium fluoride (Me4NF) gives, sequentially, the hepta- and octafluorides:
