Materials Data on Li2Bi2P2O9 by Materials Project
Li2Bi2P2O9 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.84–1.96 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with three PO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.95–2.13 Å. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 5-coordinate geometry to three O2- atoms. There are a spread of Bi–O bond distances ranging from 2.14–2.25 Å. In the second Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.17–3.04 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 two equivalent LiO4 trigonal pyramids. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one LiO4 trigonal pyramid. There are a spread of P–O bond distances ranging from 1.51–1.59 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Bi3+, and one P5+ atom. In the second O2- site, O2- is bonded in a water-like geometry to one Li1+, one Bi3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two Bi3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Bi3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+, one Bi3+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Bi3+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Li1+, one Bi3+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Bi3+ and one P5+ atom.
