Title: Materials Data on Sr3Li2Nb4O13 by Materials Project

Abstract

Li2Sr3Nb4O13 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (2.10 Å) and two longer (2.69 Å) Li–O bond lengths. There are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with eight SrO12 cuboctahedra, faces with five SrO12 cuboctahedra, and faces with eight NbO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.66–3.04 Å. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with twelve SrO12 cuboctahedra, faces with six SrO12 cuboctahedra, and faces with eight equivalent NbO6 octahedra. There are eight shorter (2.86 Å) and four longer (2.87 Å) Sr–O bond lengths. There are two inequivalent Nb+4.50+ sites. In the first Nb+4.50+ site, Nb+4.50+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six NbO6 octahedra and faces with eight SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–2°. There are a spread of Nb–O bond distances ranging from 2.02–2.06 Å. In the second Nb+4.50+ site, Nb+4.50+ ismore » bonded to six O2- atoms to form NbO6 octahedra that share corners with five NbO6 octahedra and faces with four equivalent SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–13°. There are a spread of Nb–O bond distances ranging from 1.90–2.16 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two equivalent Nb+4.50+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two Nb+4.50+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four Sr2+ and two equivalent Nb+4.50+ atoms. In the fourth O2- site, O2- is bonded to four equivalent Li1+ and one Nb+4.50+ atom to form a mixture of distorted corner and edge-sharing OLi4Nb trigonal bipyramids. In the fifth O2- site, O2- is bonded to one Li1+, two equivalent Sr2+, and two equivalent Nb+4.50+ atoms to form a mixture of distorted corner and edge-sharing OSr2LiNb2 trigonal bipyramids. In the sixth O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two equivalent Nb+4.50+ atoms. All O–Sr bond lengths are 2.87 Å. Both O–Nb bond lengths are 2.06 Å.« less
