The structure described by Li3Na(NH2)4 crystallizes in the tetragonal I-4 space group. Na(1) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent H(2) atoms. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a tetrahedral geometry to four equivalent N(1) atoms. In the second Li site, Li(2) is bonded in a 6-coordinate geometry to four equivalent N(1) and two equivalent H(1) atoms. N(1) is bonded in a distorted water-like geometry to one Na(1), one Li(1), two equivalent Li(2), one H(1), and one H(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one Li(2) and one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one Na(1) and one N(1) atom. is represented by the CIF file [CIF]
