Infobox references

Caesium sulfide is an inorganic salt with a chemical formula Cs2S. It is a strong alkali in aqueous solution. In the air, caesium sulfide emits rotten egg smelling hydrogen sulfide.

## Production

Similar to sodium sulfide, anhydrous caesium sulfide can be produced by reacting caesium and sulfur in THF. It needs ammonia or naphthalene to react.[4]

2 Cs + S → Cs

By dissolving hydrogen sulfide into caesium hydroxide solution, it will produce caesium bisulfide, then it will produce caesium sulfide too.[5][6]。

CsOH + H
2S → CsHS + H

CsHS + CsOH → Cs
2S + H
