Materials Data on Li9Al3P8O29 by Materials Project
Abstract
Li9Al3P8O29 crystallizes in the trigonal P-3c1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, 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 1.99–2.06 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent AlO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedral tilt angles are 68°. There are one shorter (1.87 Å) and three longer (2.16 Å) Li–O bond lengths. In the third Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Li–O bond lengths are 2.37 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with two equivalent LiO4 tetrahedra and corners with six PO4 tetrahedra. There is four shorter (1.91 Å) and two longer (1.92 Å) Al–O bond length. 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 AlO6 octahedra, a cornercorner with one LiO4 tetrahedra, and a cornercornermore »

The corner-sharing octahedra tilt angles range from 44–46°. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent AlO6 octahedra and a cornercorner with one LiO4 tetrahedra.

In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Al3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Al3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Li1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Al3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent P5+ atoms. In the sixth O2- site, O2- is bonded in a linear geometry to one Li1+ and one P5+ atom.},
