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 tetrafluoride, TeF 4, a stable, white, ... Some atoms can form a complex ion with four fluorine atoms which may form compounds containing the term ...
A solution of Te 2+ 4. When tellurium is treated with concentrated sulfuric acid, the result is a red solution of the Zintl ion, Te 2+ 4. [53] The oxidation of tellurium by AsF 5 in liquid SO 2 produces the same square planar cation, in addition to the trigonal prismatic, yellow-orange Te 4+ 6: [38]
Tellurium fluoride may refer to any of these compounds: Tellurium tetrafluoride, TeF 4; Tellurium hexafluoride, TeF 6; Ditellurium decafluoride, Te 2 F 10
Environmentally, tellurite [TeO 3] 2-is the more abundant anion due to tellurate's [TeO 4] 2-low solubility limiting its concentration in biospheric waters. Another way to refer to the anions is tellurium's oxyanions , which happen to be relatively stable.
Tellurium hexafluoride is a highly symmetric octahedral molecule. Its physical properties resemble those of the hexafluorides of sulfur and selenium. It is less volatile, however, due to the increase in polarizability. At temperatures below −38 °C, tellurium hexafluoride condenses to a volatile white solid.
