Title: Materials Data on K3LiNb6O15 by Materials Project

Abstract

K3LiNb6O15 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to twelve O2- atoms to form KO12 cuboctahedra that share corners with two equivalent NbO6 octahedra, faces with two equivalent KO12 cuboctahedra, and faces with eight NbO6 octahedra. The corner-sharing octahedra tilt angles range from 19–21°. There are a spread of K–O bond distances ranging from 2.83–3.10 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to eleven O2- atoms. There are a spread of K–O bond distances ranging from 2.87–3.39 Å. In the third K1+ site, K1+ is bonded in a 6-coordinate geometry to eleven O2- atoms. There are a spread of K–O bond distances ranging from 2.90–3.35 Å. Li1+ is bonded in a 2-coordinate geometry to nine O2- atoms. There are a spread of Li–O bond distances ranging from 2.06–2.79 Å. There are six inequivalent Nb+4.33+ sites. In the first Nb+4.33+ site, Nb+4.33+ is bonded to six O2- atoms to form a mixture of corner and face-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 12–67°.
