Title: Materials Data on LiNb10O18 by Materials Project

Abstract

LiNb10O18 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a distorted linear geometry to two equivalent O2- atoms. Both Li–O bond lengths are 2.75 Å. There are five inequivalent Nb+3.50+ sites. In the first Nb+3.50+ site, Nb+3.50+ is bonded to five O2- atoms to form NbO5 square pyramids that share corners with four NbO6 octahedra and corners with six NbO5 square pyramids. The corner-sharing octahedra tilt angles range from 3–45°. There are a spread of Nb–O bond distances ranging from 2.08–2.20 Å. In the second Nb+3.50+ site, Nb+3.50+ is bonded to five O2- atoms to form NbO5 square pyramids that share corners with three NbO6 octahedra, corners with five NbO5 square pyramids, and an edgeedge with one NbO6 octahedra. The corner-sharing octahedra tilt angles range from 5–55°. There are a spread of Nb–O bond distances ranging from 2.07–2.28 Å. In the third Nb+3.50+ site, Nb+3.50+ is bonded to five O2- atoms to form NbO5 square pyramids that share a cornercorner with one NbO6 octahedra, corners with five NbO5 square pyramids, and edges with two NbO6 octahedra. The corner-sharing octahedral tilt angles are 48°. There are a spread of Nb–O bond distances ranging frommore » 2.05–2.20 Å. In the fourth Nb+3.50+ site, Nb+3.50+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with two equivalent NbO6 octahedra, corners with four NbO5 square pyramids, edges with two NbO6 octahedra, and an edgeedge with one NbO5 square pyramid. The corner-sharing octahedra tilt angles range from 9–42°. There are a spread of Nb–O bond distances ranging from 2.01–2.16 Å. In the fifth Nb+3.50+ site, Nb+3.50+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with two equivalent NbO6 octahedra, corners with four NbO5 square pyramids, an edgeedge with one NbO6 octahedra, and edges with two NbO5 square pyramids. The corner-sharing octahedra tilt angles range from 9–42°. There are a spread of Nb–O bond distances ranging from 1.97–2.10 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a T-shaped geometry to three Nb+3.50+ atoms. In the second O2- site, O2- is bonded in a T-shaped geometry to three Nb+3.50+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+ and three Nb+3.50+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to three Nb+3.50+ atoms. In the fifth O2- site, O2- is bonded in a T-shaped geometry to three Nb+3.50+ atoms. In the sixth O2- site, O2- is bonded in a T-shaped geometry to three Nb+3.50+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to three Nb+3.50+ atoms. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to three Nb+3.50+ atoms. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to three Nb+3.50+ atoms.« less
