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 ...
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−
Amorphous tellurium is a black-brown powder prepared by precipitating it from a solution of tellurous acid or telluric acid (Te(OH) 6). [13] Tellurium is a semiconductor that shows greater electrical conductivity in certain directions depending on atomic alignment; the conductivity increases slightly when exposed to light ( photoconductivity ...
Selenium and tellurium form similar compounds and also the oxo-bridged species F 5 AOAF 5 (A = S, Se, Te). They are non-linear with the A-O-A angle of 142.5, 142.4 and 145.5° for S, Se and Te, respectively. [12] The tellurium anion F 5 TeO −, known as teflate, is a large and rather stable anion, useful for forming stable salts with large ...
Tellurium fluoride may refer to any of these compounds: Tellurium tetrafluoride, TeF 4; Tellurium hexafluoride, TeF 6;
A tetrafluoride is a chemical compound with ... Some atoms can form a complex ion with four fluorine atoms which may form compounds containing the term tetrafluoride ...
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 ...
