title: Materials Data on AsP3(PbO8)2 by Materials Project

description: AsP3(PbO8)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Pb sites. In the first Pb site, Pb is bonded to six O atoms to form distorted PbO6 octahedra that share corners with two equivalent AsO4 tetrahedra and corners with four PO4 tetrahedra. There are a spread of Pb–O bond distances ranging from 2.16–2.21 Å. In the second Pb site, Pb is bonded to six O atoms to form PbO6 octahedra that share a cornercorner with one AsO4 tetrahedra and corners with five PO4 tetrahedra. There are a spread of Pb–O bond distances ranging from 2.17–2.22 Å. As is bonded to four O atoms to form AsO4 tetrahedra that share corners with three PbO6 octahedra. The corner-sharing octahedra tilt angles range from 30–56°. There are a spread of As–O bond distances ranging from 1.69–1.82 Å. There are three inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with three PbO6 octahedra. The corner-sharing octahedra tilt angles range from 18–46°. There are a spread of P–O bond distances ranging from 1.52–1.65 Å. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with three PbO6 octahedra. The corner-sharing octahedra tilt angles range from 25–52°. There are a spread of P–O bond distances ranging from 1.52–1.65 Å. In the third P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with three PbO6 octahedra. The corner-sharing octahedra tilt angles range from 26–49°. There are a spread of P–O bond distances ranging from 1.51–1.65 Å. There are sixteen inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Pb and one P atom. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one Pb and one P atom. In the third O site, O is bonded in a distorted single-bond geometry to one P atom. In the fourth O site, O is bonded in a distorted single-bond geometry to one P and one O atom. The O–O bond length is 1.48 Å. In the fifth O site, O is bonded in a distorted single-bond geometry to one P atom. In the sixth O site, O is bonded in a distorted water-like geometry to one As and one O atom. In the seventh O site, O is bonded in a distorted bent 150 degrees geometry to one Pb and one P atom. In the eighth O site, O is bonded in a bent 150 degrees geometry to one Pb and one P atom. In the ninth O site, O is bonded in a bent 150 degrees geometry to one Pb and one As atom. In the tenth O site, O is bonded in a distorted single-bond geometry to one Pb and one P atom.
