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.
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. There are a spread of Li(1)-N(1) bond distances ranging from 2.02-2.17 Å. In the second Li site, Li(2) is bonded to four equivalent N(1) atoms to form distorted edge-sharing LiN4 tetrahedra. There are two shorter (2.13 Å) and two longer (2.15 Å) Li(2)-N(1) bond lengths. N(1) is bonded in a distorted single-bond geometry to two equivalent Li(2), four equivalent Li(1), and one H(1) atom. The N(1)-H(1) bond length is 1.04 Å. H(1) is bonded in a single-bond geometry to one N(1) atom.
