Li(NH3)4Te is Silicon tetrafluoride-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one ditellurium molecule and two Li(NH3)4 clusters. In each Li(NH3)4 cluster, Li1+ is bonded in a tetrahedral geometry to four N3- atoms. There are a spread of Li–N bond distances ranging from 2.05–2.12 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded to one Li1+ and three H1+ atoms to form distorted corner-sharing NLiH3 tetrahedra. All N–H bond lengths are 1.03 Å. In the second N3- site, N3- is bonded to one Li1+ and three H1+ atoms to form distorted corner-sharing NLiH3 tetrahedra. There is one shorter (1.02 Å) and two longer (1.03 Å) N–H bond length. In the third N3- site, N3- is bonded to one Li1+ and three H1+ atoms to form distorted corner-sharing NLiH3 tetrahedra. All N–H bond lengths are 1.03 Å. In the fourth N3- site, N3- is bonded to one Li1+ and three H1+ atoms to form distorted corner-sharing NLiH3 tetrahedra. There is one shorter (1.02 Å) and two longer (1.03 Å) N–H bond length. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eleventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom.
