Materials Data on P3PbNO9 by Materials Project

(PbP3O9)2N2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of eight ammonia molecules and one PbP3O9 framework. In the PbP3O9 framework, there are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.33–3.06 Å. In the second Pb2+ site, Pb2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.34–2.87 Å. There are six 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 1.51–1.63 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 1.49–1.63 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 1.49–1.62 Å. In the fourth 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 fifth 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 sixth 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 1.49–1.62 Å. There are eighteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to two Pb2+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to one Pb2+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the thirteenth O2- site, O2- is bonded in a single-bond geometry to one Pb2+ and one P5+ atom. In the fourteenth O2- site, O2- is bonded in a single-bond geometry to one Pb2+ and one P5+ atom. In the fifteenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the sixteenth O2- site, O2- is bonded in a single-bond geometry to two equivalent Pb2+ and one P5+ atom. In the seventeenth O2- site, O2- is bonded in a single-bond geometry to one Pb2+ and one P5+ atom. In the eighteenth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms.
