Materials Data on PH5N2O3 by Materials Project
NH2(NH)2P2NH6O6 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four ammonia molecules, two ammonia molecules, and one P2NH6O6 cluster. In the P2NH6O6 cluster, there are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.51–1.63 Å. In the second P5+ site, P5+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.64 Å) and two longer (1.65 Å) P–O bond length. N2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are a spread of N–H bond distances ranging from 1.04–1.08 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.02 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth 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 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 distorted single-bond geometry to one N2- and one O2- atom. The H–O bond length is 1.64 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the third O2- site, O2- is bonded in a water-like geometry to one P5+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a water-like geometry to one P5+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom.
