Materials Data on H3N by Materials Project

NH3 is Ammonia-like structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of four ammonia molecules. N3- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. All N–H bond lengths are 1.03 Å. 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.

Materials Data on HN by Materials Project

N4H3NH2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules and four N4H3 clusters. In each N4H3 cluster, there are four inequivalent N1- sites. In the first N1- site, N1- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are a spread of N–H bond distances ranging from 1.05–1.08 Å. In the second N1- site, N1- is bonded in a linear geometry to two N1- atoms. There is one shorter (1.18 Å) and one longer (1.19 Å) N–N bond length. In the third N1- site, N1- is bonded in a distorted bent 120 degrees geometry to one N1- and one H1+ atom. The N–H bond length is 1.71 Å. In the fourth N1- site, N1- is bonded in a single-bond geometry to one N1- atom. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two N1- atoms. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N1- atom.
