A selenide is a chemical compound containing a selenium with oxidation number of −2. Similar to sulfide , selenides occur both as inorganic compounds and as organic derivatives, which are called organoselenium compound .
Hydrogen selenide is an inorganic compound with the formula H 2 Se. This hydrogen chalcogenide is the simplest and most commonly encountered hydride of selenium. H 2 Se is a colorless, flammable gas under standard conditions. It is the most toxic selenium compound [3] with an exposure limit of 0.05 ppm over an 8-hour period.
Selenium occurs naturally in a number of inorganic forms, including selenide, selenate, and selenite, but these minerals are rare. The common mineral selenite is not a selenium mineral, and contains no selenite ion , but is rather a type of gypsum (calcium sulfate hydrate) named like selenium for the moon well before the discovery of selenium.
Cadmium selenide is an inorganic compound with the formula Cd Se. It is a black to red-black solid that is classified as a II-VI semiconductor of the n-type . It is a pigment, but applications are declining because of environmental concerns.
Lithium selenide is an inorganic compound that formed by selenium and lithium.It is a selenide with a chemical formula Li 2 Se. Lithium selenide has the same crystal form as other selenides, which is cubic, belonging to the anti-fluorite structure, the space group is ¯, each unit cell has 4 units.
