A hydroselenide (or biselenide or selanide) is an ion or chemical compound containing the [SeH]− ion. The radical HSe is a pseudohalogen. Hydroselenide can be a ligand in transition metal complexes where it can be attached to a single atom, or bridge two atoms. The terms used in ligand naming are selanido, or hydrogenselenido.[1]

Similar compounds include the hydrosulfides, and hydrotellurides. Related compounds include toxic hydrogen selenide gas, hydrodiselenides (HSeSe−) and the hydride selenides that do not have a bond between hydrogen and selenium.

Production

HSe− complexes may be formed by reacting H2Se with a reduced metal complex, forming a hydrido-hyrogenselenido complex. A halide ligand in a complex may be replaced by HSe− from sodium hydroselenide.

A metal-metal bond can be replaced by a selenium bridge, that can then be protonated to yield a bridged complex.[2]

Properties

Hydroselenides easily react with water or water vapour to produce the malodourous hydrogen selenide.

Hydroselenide occurs naturally in alkaline, oxygen-free waters.[3]

Use

Hydroselenides have been used to introduce selenium into organic compounds, such as replacing a methylsufide group with selenium.[4][5]
