Lithium sulfide

Lithium sulfide is the inorganic compound with the formula Li2S.

It forms a solid yellow-white deliquescent powder.

In air, it easily hydrolyses to release foul smelling hydrogen sulfide gas.

This reaction is conveniently conducted in anhydrous ammonia.

[3] The THF-soluble triethylborane adduct of lithium sulfide can be generated using superhydride.
