Tellurium tetrafluoride, TeF 4, is a stable, white, hygroscopic crystalline solid and is one of two fluorides of tellurium. The other binary fluoride is tellurium hexafluoride . [ 1 ] The widely reported Te 2 F 10 has been shown to be F 5 TeOTeF 5 [ 1 ] There are other tellurium compounds that contain fluorine, but only the two mentioned ...
Tellurium compounds are compounds containing the element tellurium (Te). Tellurium belongs to the chalcogen (group 16) family of elements on the periodic table, which also includes oxygen, sulfur, selenium and polonium: Tellurium and selenium compounds are similar. Tellurium exhibits the oxidation states −2, +2, +4 and +6, with +4 being most ...

Tellurium fluoride may refer to any of these compounds: Tellurium tetrafluoride, TeF 4; Tellurium hexafluoride, TeF 6;
Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals.
Compounds that contain the anions follow basic nomenclature rules, the cation is named first, followed by the anion. [2] As individual ions current IUPAC naming conventions dictate that compounds containing what was conventionally known as the tellurite ion, [TeO 3 ] 2- , be named as tellurate (IV) compounds, while other tellurates are labeled ...
The crystal structures of both selenium tetrafluoride and tellurium tetrafluoride are known. Chalcogen chlorides and bromides have also been explored. In particular, selenium dichloride and sulfur dichloride can react to form organic selenium compounds. Dichalcogen dihalides, such as Se 2 Cl 2 also are known to exist. There are also mixed ...
Despite the low reactivity of the tetrafluoroborate anion in general, BF − 4 serves as a fluorine source to deliver an equivalent of fluoride. [2] The Balz–Schiemann reaction for the synthesis of aryl fluorides is the best known example of such a reaction. [3]
