Materials Data on Sr3Li6Nb2O11 by Materials Project
Abstract
Li6Sr3Nb2O11 crystallizes in the orthorhombic Pmma space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra, corners with two equivalent LiO5 trigonal bipyramids, corners with two equivalent NbO5 trigonal bipyramids, an edgeedge with one NbO6 octahedra, and an edgeedge with one LiO4 tetrahedra. There are two shorter (2.03 Å) and two longer (2.09 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share corners with three LiO4 tetrahedra, a cornercorner with one NbO5 trigonal bipyramid, edges with two equivalent NbO6 octahedra, an edgeedge with one LiO4 tetrahedra, and an edgeedge with one LiO5 trigonal bipyramid. There are three shorter (2.12 Å) and two longer (2.23 Å) Li–O bond lengths. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent NbO6 octahedra, corners with three LiO4 tetrahedra, a cornercorner with one LiO5 trigonal bipyramid, corners with two equivalent NbO5 trigonal bipyramids, and an edgeedge with one LiO5 trigonal bipyramid.more »

In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.55–2.81 Å. In the second Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.49–2.76 Å. There are two inequivalent Nb5+ sites.

In the first O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Li1+, two equivalent Sr2+, and one Nb5+ atom. In the second O2- site, O2- is bonded in a 6-coordinate geometry to two equivalent Li1+, three Sr2+, and one Nb5+ atom.
