Tetraselenium tetranitride is the inorganic compound with the formula Se 4 N 4. Like the analogous tetrasulfur tetranitride S 4 N 4, Se 4 N 4 is an orange solid. It is however less soluble and more shock-sensitive than S 4 N 4. [2] As determined by X-ray crystallography, Se 4 N 4 adopts a cage structure similar to that of S 4 N 4.
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 ...
Tetrasulfur tetranitride is an inorganic compound with the formula S 4 N 4. This vivid orange, opaque, crystalline explosive is the most important binary sulfur nitride, which are compounds that contain only the elements sulfur and nitrogen. It is a precursor to many S-N compounds and has attracted wide interest for its unusual structure and ...
Selenium tetrafluoride (Se F 4) is an inorganic compound.It is a colourless liquid that reacts readily with water. It can be used as a fluorinating reagent in organic syntheses (fluorination of alcohols, carboxylic acids or carbonyl compounds) and has advantages over sulfur tetrafluoride in that milder conditions can be employed and it is a liquid rather than a gas.
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
Selenium tetrabromide exists in two polymorphs, the trigonal, black α-SeBr 4 and the monoclinic, orange-reddish β-SeBr 4, both of which feature tetrameric cubane-like Se 4 Br 16 units but differ in how they are arranged. [1]
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds . There is no complete list of chemical compounds since by nature the list would be infinite.
In these compounds, selenium plays a role analogous to that of sulfur. Another naturally occurring organoselenium compound is dimethyl selenide. [57] [58] Certain soils are selenium-rich, and selenium can be bioconcentrated by some plants. In soils, selenium most often occurs in soluble forms such as selenate (analogous to sulfate), which are ...
