The compound described by Li3(NH)2 crystallizes in the orthorhombic Iba2 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. In the second Li site, Li(2) is bonded to four equivalent N(1) atoms to form distorted edge-sharing LiN4 tetrahedra. N(1) is bonded in a distorted single-bond geometry to two equivalent Li(2), four equivalent Li(1), and one H(1) atom. H(1) is bonded in a single-bond geometry to one N(1) atom. is represented by the CIF file [CIF]
