Materials Data on Bi3(PO5)2 by Materials Project

Abstract

Bi3(PO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Bi+3.33+ sites. In the first Bi+3.33+ site, Bi+3.33+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.20–2.88 Å. In the second Bi+3.33+ site, Bi+3.33+ is bonded to seven O2- atoms to form distorted BiO7 pentagonal bipyramids that share corners with five PO4 tetrahedra. There are a spread of Bi–O bond distances ranging from 2.28–2.62 Å. In the third Bi+3.33+ site, Bi+3.33+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Bi–O bond distances ranging from 2.24–2.96 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent BiO7 pentagonal bipyramids. There is one shorter (1.54 Å) and three longer (1.56 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent BiO7 pentagonal bipyramids. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded to four Bi+3.33+ atoms to form distorted edge-sharing OBi4 tetrahedra. In the second O2- site, O2- is bonded in a trigonal planar geometry to three Bi+3.33+ atoms. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Bi+3.33+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two Bi+3.33+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two Bi+3.33+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two Bi+3.33+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Bi+3.33+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two Bi+3.33+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Bi+3.33+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to two Bi+3.33+ and one P5+ atom.
