Lithium imide is an inorganic compound with the chemical formula Li
2NH. This white solid can be formed by a reaction between lithium amide and lithium hydride.
The product is light-sensitive and can undergo disproportionation to form lithium nitride, which is characteristically red.
Lithium imide is thought to have a simple face-centered cubic structure with a Fm3m space group; with N-H bond distances of 0.82(6) Å and a H–N–H bond angle of 109.5°, giving it a similar structure to lithium amide.
Lithium imide is strongly basic and could have uses in organic and organometallic chemistry. It has been investigated as a material for hydrogen storage.
