Title: Materials Data on LiTa3O8 by Materials Project

Abstract

LiTa3O8 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.16–2.35 Å. There are four inequivalent Ta5+ sites. In the first Ta5+ site, Ta5+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with six TaO6 octahedra and an edgeedge with one TaO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 0–35°. There are a spread of Ta–O bond distances ranging from 1.88–2.10 Å. In the second Ta5+ site, Ta5+ is bonded to seven O2- atoms to form TaO7 pentagonal bipyramids that share corners with two equivalent TaO7 pentagonal bipyramids and edges with five TaO6 octahedra. There are a spread of Ta–O bond distances ranging from 1.94–2.13 Å. In the third Ta5+ site, Ta5+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with six TaO6 octahedra and an edgeedge with one TaO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 2–42°. There are a spread of Ta–O bond distances ranging from 1.94–2.08 Å. In the fourth Ta5+ site, Ta5+ is bonded to six O2- atoms tomore » form TaO6 octahedra that share corners with six TaO6 octahedra and an edgeedge with one TaO7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 3–42°. There are a spread of Ta–O bond distances ranging from 1.93–2.03 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent Ta5+ atoms. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to two equivalent Li1+ and two equivalent Ta5+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three Ta5+ atoms. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Ta5+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to two equivalent Ta5+ atoms. In the sixth O2- site, O2- is bonded to two equivalent Li1+ and two Ta5+ atoms to form distorted corner-sharing OLi2Ta2 tetrahedra. In the seventh O2- site, O2- is bonded in a distorted T-shaped geometry to three Ta5+ atoms. In the eighth O2- site, O2- is bonded in a T-shaped geometry to one Li1+ and two equivalent Ta5+ atoms. In the ninth O2- site, O2- is bonded in a linear geometry to two equivalent Ta5+ atoms. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to three Ta5+ atoms.« less
