Materials Data on KPH3NO3 by Materials Project
KPNH3O3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.74–2.99 Å. In the second K1+ site, K1+ is bonded in a 4-coordinate geometry to two H1+ and six O2- atoms. There are one shorter (2.76 Å) and one longer (3.04 Å) K–H bond lengths. There are a spread of K–O bond distances ranging from 2.71–2.98 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to two N3- and two O2- atoms to form corner-sharing PN2O2 tetrahedra. There is one shorter (1.68 Å) and one longer (1.69 Å) P–N bond length. Both P–O bond lengths are 1.52 Å. In the second P5+ site, P5+ is bonded to two N3- and two O2- atoms to form corner-sharing PN2O2 tetrahedra. There is one shorter (1.68 Å) and one longer (1.70 Å) P–N bond length. There is one shorter (1.51 Å) and one longer (1.53 Å) P–O bond length. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted trigonal planar geometry to two P5+ and one H1+ atom. The N–H bond length is 1.04 Å. In the second N3- site, N3- is bonded in a 3-coordinate geometry to two P5+ and one H1+ atom. The N–H bond length is 1.03 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. 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 K1+ and one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two K1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two K1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to two K1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one P5+ atom.
