Materials Data on LiNbPO5 by Materials Project
Abstract
LiNbPO5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with two equivalent NbO6 octahedra, corners with two equivalent PO4 tetrahedra, edges with two equivalent NbO6 octahedra, an edgeedge with one LiO5 square pyramid, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–63°. There are a spread of Li–O bond distances ranging from 2.06–2.36 Å. In the second Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 2.02–2.40 Å. There are two inequivalent Nb4+ sites. In the first Nb4+ site, Nb4+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with two equivalent NbO6 octahedra, corners with two equivalent LiO5 square pyramids, and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 41–44°. There are a spread of Nb–O bond distances ranging from 1.90–2.18 Å. In the second Nb4+ site, Nb4+ is bonded to six O2- atoms to form NbO6 octahedra that share cornersmore »
