Title: Materials Data on LiNb2O4 by Materials Project

Abstract

LiNb2O4 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six NbO6 pentagonal pyramids, edges with two equivalent LiO6 octahedra, and edges with six NbO6 pentagonal pyramids. There are four shorter (2.18 Å) and two longer (2.21 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six NbO6 pentagonal pyramids, edges with two equivalent LiO6 octahedra, and edges with six NbO6 pentagonal pyramids. There are a spread of Li–O bond distances ranging from 2.17–2.24 Å. There are four inequivalent Nb+3.50+ sites. In the first Nb+3.50+ site, Nb+3.50+ is bonded to six O2- atoms to form distorted NbO6 pentagonal pyramids that share corners with three equivalent LiO6 octahedra, edges with three LiO6 octahedra, and edges with six NbO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 5–10°. There are three shorter (2.11 Å) and three longer (2.14 Å) Nb–O bond lengths. In the second Nb+3.50+ site, Nb+3.50+ is bonded to six O2- atoms to form distorted NbO6more » pentagonal pyramids that share corners with three equivalent LiO6 octahedra, edges with three LiO6 octahedra, and edges with six NbO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 5–10°. There are a spread of Nb–O bond distances ranging from 2.11–2.14 Å. In the third Nb+3.50+ site, Nb+3.50+ is bonded to six O2- atoms to form distorted NbO6 pentagonal pyramids that share corners with three equivalent LiO6 octahedra, edges with three LiO6 octahedra, and edges with six NbO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 6–10°. There are three shorter (2.11 Å) and three longer (2.14 Å) Nb–O bond lengths. In the fourth Nb+3.50+ site, Nb+3.50+ is bonded to six O2- atoms to form distorted NbO6 pentagonal pyramids that share corners with three equivalent LiO6 octahedra, edges with three LiO6 octahedra, and edges with six NbO6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 5–9°. There are a spread of Nb–O bond distances ranging from 2.11–2.14 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+ and three Nb+3.50+ atoms to form a mixture of corner and edge-sharing OLi2Nb3 square pyramids. In the second O2- site, O2- is bonded to two equivalent Li1+ and three Nb+3.50+ atoms to form a mixture of corner and edge-sharing OLi2Nb3 square pyramids. In the third O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Nb+3.50+ atoms. In the fourth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Nb+3.50+ atoms. In the fifth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Nb+3.50+ atoms. In the sixth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Nb+3.50+ atoms. In the seventh O2- site, O2- is bonded to two equivalent Li1+ and three Nb+3.50+ atoms to form a mixture of corner and edge-sharing OLi2Nb3 square pyramids. In the eighth O2- site, O2- is bonded to two equivalent Li1+ and three Nb+3.50+ atoms to form a mixture of corner and edge-sharing OLi2Nb3 square pyramids.« less
