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 → Cs2S
By dissolving hydrogen sulfide into caesium hydroxide solution, it will produce caesium bisulfide, then it will produce caesium sulfide too.[5][6]。
- CsOH + H2S → CsHS + H2O
- CsHS + CsOH → Cs2S + H2O
