Hydrogen diselenide

Summary

Hydrogen diselenide is an inorganic selenium compound with a chemical formula H2Se2 or (SeH)2.[1][2] At room temperature, hydrogen diselenide dissociates easily to hydrogen selenide (H2Se) and elemental selenium, and is therefore not stable. However, hydrogen diselenide can be stable in some solutions.[3]
