The material structure described by LiNa2(NH2)3 crystallizes in the tetragonal P4_2/m space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a 8-coordinate geometry to two equivalent N(1), two equivalent N(2), two equivalent H(1), and two equivalent H(3) atoms. In the second Na site, Na(2) is bonded in a distorted trigonal pyramidal geometry to four equivalent N(1) atoms. In the third Na site, Na(3) is bonded in a 14-coordinate geometry to two equivalent N(2), four equivalent N(1), four equivalent H(2), and four equivalent H(3) atoms. Li(1) is bonded in a distorted trigonal non-coplanar geometry to one N(2) and two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted water-like geometry to one Na(1), one Na(2), one Na(3), one Li(1), one H(1), and one H(2) atom. In the second N site, N(2) is bonded in a 2-coordinate geometry to one Na(3), two equivalent Na(1), one Li(1), and two equivalent H(3) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one Na(1) and one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one Na(3) and one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one Na(1), one Na(3), and one N(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
