Materials Data on LiBiP2O7 by Materials Project

Abstract

LiBiP2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.63 Å. Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.37–2.80 Å. There are two 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 1.52–1.63 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 1.52–1.61 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+, one Bi3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+, one Bi3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Li1+, one Bi3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Bi3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Bi3+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Bi3+ and one P5+ atom.
