Selenium compounds are compounds containing the element selenium (Se). Among these compounds, selenium has various oxidation states, the most common ones being −2, +4, and +6. Selenium compounds exist in nature in the form of various minerals, such as clausthalite, guanajuatite, tiemannite, crookesite etc., and can also coexist with sulfide ...
Selenium hexafluoride is the inorganic compound with the formula SeF 6. It is a very toxic colourless gas described as having a "repulsive" odor. [ 5 ] It is not widely encountered and has no commercial applications.
Selenium dibromide – SeBr 2; Selenium dioxide – SeO 2; Selenium disulfide – SeS 2; Selenium hexafluoride – SeF 6; Selenium hexasulfide – Se 2 S 6; Selenium oxybromide – SeOBr 2; Selenium oxydichloride – SeOCl 2; Selenium tetrachloride – SeCl 4; Selenium tetrafluoride – SeF 4; Selenium trioxide – SeO 3; Selenoyl fluoride ...
Organoselenium chemistry is the science exploring the properties and reactivity of organoselenium compounds, chemical compounds containing carbon-to-selenium chemical bonds. [ 1 ] [ 2 ] [ 3 ] Selenium belongs with oxygen and sulfur to the group 16 elements or chalcogens, and similarities in chemistry are to be expected.
Selenium compounds commonly exist in the oxidation states −2, +2, +4, and +6. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. [15]

Selenium chloride may refer to the following chemical compounds: Selenium monochloride, Se 2 Cl 2; Selenium dichloride, SeCl 2;
As indicated by the fact that only a few thousand tons of selenium are produced annually, the subset of selenium compounds called selenides find few applications. Commercially significant is zinc selenide, which is used in some infrared optics. Cadmium selenide is a pigment but its use has been declining because of environmental considerations.
