[1] The widely reported Te2F10 has been shown to be F5TeOTeF5 [1] There are other tellurium compounds that contain fluorine, but only the two mentioned contain solely tellurium and fluorine.

[1] Tellurium tetrafluoride can be prepared by the following reaction: It is also prepared by reacting nitryl fluoride with tellurium or from the elements at 0 °C or by reacting selenium tetrafluoride with tellurium dioxide at 80 °C.

Copper, silver, gold or nickel will react with tellurium tetrafluoride at 185 °C.

In the solid phase, it consists of infinite chains of TeF3F2/2 in an octahedral geometry.

A lone pair of electrons occupies the sixth position.
