Materials Data on LiPH21S3N7 by Materials Project
Li(NH3)4NH4NH3PNH2S3 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two ammonia molecules, two ammonium molecules, two Li(NH3)4 clusters, and two PNH2S3 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 2.05–2.08 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. There is one shorter (1.02 Å) and two longer (1.03 Å) N–H bond length. 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. There is one shorter (1.02 Å) and two longer (1.03 Å) N–H bond length. In the fourth N3- site, N3- is bonded to one Li1+ and three H1+ atoms to form distorted corner-sharing NLiH3 tetrahedra. There is two shorter (1.02 Å) and one 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. In each PNH2S3 cluster, P5+ is bonded in a tetrahedral geometry to one N3- and three S2- atoms. The P–N bond length is 1.71 Å. There are a spread of P–S bond distances ranging from 2.02–2.06 Å. N3- is bonded in a distorted trigonal non-coplanar geometry to one P5+ and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. There are two 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. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a single-bond geometry to one P5+ atom. In the second S2- site, S2- is bonded in a single-bond geometry to one P5+ atom. In the third S2- site, S2- is bonded in a single-bond geometry to one P5+ atom.
