Materials Data on P2H12N8O3 by Materials Project
P2N7H12NO3 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two nitric acid molecules and two P2N7H12 clusters. In each P2N7H12 cluster, there are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four N2- atoms to form corner-sharing PN4 tetrahedra. There are a spread of P–N bond distances ranging from 1.59–1.66 Å. In the second P5+ site, P5+ is bonded to four N2- atoms to form corner-sharing PN4 tetrahedra. There are a spread of P–N bond distances ranging from 1.59–1.66 Å. There are seven inequivalent N2- sites. In the first N2- site, N2- 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. In the second N2- site, N2- is bonded in a distorted trigonal non-coplanar geometry to one P5+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the third N2- site, N2- 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. In the fourth N2- site, N2- 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. In the fifth N2- site, N2- 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. In the sixth N2- site, N2- is bonded in a distorted trigonal planar geometry to one P5+ and two H1+ atoms. Both N–H bond lengths are 1.02 Å. In the seventh N2- site, N2- is bonded in a bent 120 degrees geometry to two P5+ atoms. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the eleventh H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one N2- atom.
