Germanium diselenide explained

Germanium diselenide is an inorganic compound, with the chemical formula of GeSe₂.

Preparation

Germanium diselenide is prepared by reacting stoichiometric amounts of germanium and selenium or by reacting germanium tetrachloride with hydrogen selenide:

Properties

Germanium diselenide reacts with selenium and hydrazine to obtained yellow (N₂H₅)₄Ge₂Se₆, a selenidogermanate.^[1]

It reacts with lead selenide and gallium(III) selenide at high temperatures to obtain PbGa₂GeSe₆.^[2]
