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 ...
The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1] In principle, Te 2− is formed by the two-e − reduction of tellurium. The redox potential is −1.14 V. [2] Te(s) + 2 e − ↔ Te 2−
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.
The most important oxidation state of thorium is +4, represented in compounds such as thorium dioxide (ThO 2) and thorium tetrafluoride (ThF 4), although some compounds are known with thorium in lower formal oxidation states. [12] [13] [14] Owing to thorium(IV)'s lack of electrons in 6d and 5f orbitals, the tetravalent thorium compounds are ...
Tellurium tetrachloride is the gateway compound for high valent organotellurium compounds. Arylation gives, depending on conditions, Te(C 6 H 4 R) 2 Cl 2, [Te(C 6 H 4 R) 5] −, [Te(C 6 H 4 R) 6] 2−. [6] TeCl 4 has few applications in organic synthesis. Its equivalent weight is high, and the toxicity of organotellurium compounds is problematic.
