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;
A tetrafluoride is a chemical compound with four fluorines in its formula. ... Tellurium tetrafluoride, TeF 4, a stable, ... Ions Some atoms can form a complex ion ...
The heavier chalcogens sulfur, selenium, and tellurium are known to form thorium chalcogenides, many of which have more complex structure than the oxides. Apart from several binary compounds, the oxychalcogenides ThOS (yellow), ThOSe, and ThOTe are also known. [29]
A tellurite fluoride is a mixed anion compound containing tellurite and fluoride ions. They have also been called oxyfluorotellurate(IV) where IV is the oxidation state of tellurium in tellurite. Comparable compounds are sulfite fluorides or selenite fluorides.
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 ...
