Li₂NH (antifluorite) & LiNH₂ (defect antifluorite)

Click on the structures above to display in 3D

Both Li₂NH and LiNH₂have the ability to store hydrogen within their structures. This storage ability is dependant upon ion mobility, the Li⁺ ions are able to migrate throughout the structure, involving transitory defect sites. Uptake of H₂ can occur by protonation of NH₂^–.
