Materials Data on Bi(PO3)4 by Materials Project

Abstract

Bi(PO3)4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Bi5+ is bonded to seven O2- atoms to form distorted BiO7 pentagonal bipyramids that share corners with seven PO4 tetrahedra. There are a spread of Bi–O bond distances ranging from 2.31–2.57 Å. There are four inequivalent P+4.75+ sites. In the first P+4.75+ site, P+4.75+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent BiO7 pentagonal bipyramids and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.48–1.62 Å. In the second P+4.75+ site, P+4.75+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent BiO7 pentagonal bipyramids and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.64 Å. In the third P+4.75+ site, P+4.75+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one BiO7 pentagonal bipyramid and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.51–1.60 Å. In the fourth P+4.75+ site, P+4.75+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent BiO7 pentagonal bipyramids and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P+4.75+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one P+4.75+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P+4.75+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two P+4.75+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P+4.75+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to two P+4.75+ atoms. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P+4.75+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P+4.75+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P+4.75+ atom. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to two P+4.75+ atoms. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P+4.75+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to one Bi5+ and one P+4.75+ atom.
