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. When an aluminum-reduced hydrochloric acid solution of selenium dioxide is reacted with lead acetate, the resulting black precipitate contains lead diselenide (PbSe2)，this proves that hydrogen diselenide exists in the gas mixture.[3]However, hydrogen diselenide can be stable in some solutions.[3]
