Selenium dichloride is an important reagent in the preparation of selenium compounds (e.g. the preparation of Se 7). It is prepared by treating selenium with sulfuryl chloride (SO 2 Cl 2 ). [ 10 ] Selenium reacts with fluorine to form selenium hexafluoride :
Selenium monochloride or diselenium dichloride is an inorganic compound with the formula Se 2 Cl 2. Although a common name for the compound is selenium monochloride, reflecting its empirical formula , IUPAC does not recommend that name, instead preferring the more descriptive diselenium dichloride.
Selenium chloride may refer to the following chemical compounds: Selenium monochloride, Se 2 Cl 2; Selenium dichloride, SeCl 2; Selenium tetrachloride, SeCl 4
[1] [2] [3] Selenium belongs with oxygen and sulfur to the group 16 elements or chalcogens, and similarities in chemistry are to be expected. Organoselenium compounds are found at trace levels in ambient waters, soils and sediments. [4] Selenium can exist with oxidation state −2, +2, +4, +6. Se(II) is the dominant form in organoselenium ...
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
A hexachloride is a compound or ion that contains six chlorine atoms or ions. It is the highest chloride that an element can form. Common hexachlorides include: Molybdenum hexachloride, MoCl 6; Tungsten hexachloride, WCl 6; Rhenium hexachloride, ReCl 6; Uranium hexachloride, UCl 6; Some hexachloroanions are also known: Hexachloroaluminate [AlCl ...
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.
