Hydrogen diselenide is an inorganic selenium compound with a chemical formula H₂Se₂ or (SeH)₂.^[2]^[3] 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.^[4]
