Quick Facts Names, Identifiers ...

Preparation

Germanium diselenide is prepared by reacting stoichiometric amounts of germanium and selenium or by reacting germanium tetrachloride with hydrogen selenide:[1]

Ge + 2Se → GeSe2
GeCl4 + 2H2Se → GeSe2 + 4HCl

Properties

Germanium diselenide reacts with selenium and hydrazine to obtained yellow (N2H5)4Ge2Se6, a selenidogermanate.[2]

2GeSe2 + 2Se + 5N2H4 → (N2H5)4Ge2Se6 + N2

It reacts with lead selenide and gallium(III) selenide at high temperatures to obtain PbGa2GeSe6.[3]
