Selenide

Selenide

The selenide ion is Se2−.

A selenide is a chemical compound in which selenium serves as an anion with oxidation number of −2, much as sulfur does in a sulfide.

Examples

* hydrogen selenide, H2Se
* sodium selenide, Na2Se

See for a list.

Discussion

The chemistry of the selenides parallels that of the sulfides.

Similar to sulfide, for an aqueous solution, selenide ion, Se2−, is prevalent only in very basic conditions. In neutral conditions, hydrogen selenide ion, HSe−, is most common. In acid conditions, hydrogen selenide, H2Se, is formed.
