title: Materials Data on P6H26N7ClO19 by Materials Project

description: (NH4)12(P6NO18)2(H2O)2Cl2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of twelve ammonium molecules; two hydrochloric acid molecules; two water molecules; and two P6NO18 ribbons oriented in the (1, 0, 0) direction. In one of the P6NO18 ribbons, 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 1.50–1.63 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 1.50–1.62 Å. In the third 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 1.50–1.63 Å. N+2.43- is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.93 Å) and two longer (3.04 Å) N–O bond lengths. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one P5+ atom. In the second O2- site, O2- is bonded in a 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 single-bond geometry to one P5+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one P5+ and one N+2.43- atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the seventh O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one P5+ and one N+2.43- atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In one of the P6NO18 ribbons, there are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 70°. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one NO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 68°. There are a spread of P–O bond distances ranging from 1.49–1.62 Å. N+2.43- is bonded to six O2- atoms to form distorted NO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of N–O bond distances ranging from 2.96–3.09 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 single-bond geometry to one P5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one P5+ and one N+2.43- atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one P5+ and one N+2.43- atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the seventh O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one P5+ and one N+2.43- atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms.
