Materials Data on P3H11N4O9 by Materials Project
NH3NH2P3N2H6O9 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two ammonia molecules; two ammonia molecules; and one P3N2H6O9 sheet oriented in the (1, 0, 0) direction. In the P3N2H6O9 sheet, there are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.64 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.63 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There is two shorter (1.50 Å) and two longer (1.62 Å) P–O bond length. There are two inequivalent N2- sites. In the first N2- site, N2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There is one shorter (1.05 Å) and two longer (1.08 Å) N–H bond length. In the second N2- site, N2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are a spread of N–H bond distances ranging from 1.06–1.08 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to one N2- and one O2- atom. The H–O bond length is 1.58 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to one N2- and one O2- atom. The H–O bond length is 1.59 Å. 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 distorted linear geometry to one N2- and one O2- atom. The H–O bond length is 1.59 Å. In the sixth H1+ site, H1+ is bonded in a distorted single-bond geometry to one N2- and one O2- atom. The H–O bond length is 1.64 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one P5+ and one H1+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom.
