Materials Data on Li4TbF8 by Materials Project
Abstract
Li4TbF8 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six F1- atoms to form a mixture of edge and corner-sharing LiF6 octahedra. The corner-sharing octahedra tilt angles range from 20–40°. There are a spread of Li–F bond distances ranging from 1.99–2.09 Å. In the second Li1+ site, Li1+ is bonded to six F1- atoms to form a mixture of distorted edge and corner-sharing LiF6 octahedra. The corner-sharing octahedra tilt angles range from 18–60°. There are a spread of Li–F bond distances ranging from 1.96–2.30 Å. Tb4+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Tb–F bond distances ranging from 2.24–2.38 Å. There are five inequivalent F1- sites. In the first F1- site, F1- is bonded to four Li1+ and one Tb4+ atom to form distorted FLi4Tb square pyramids that share a cornercorner with one FLi4Tb square pyramid, corners with eight FLi3Tb trigonal pyramids, edges with two equivalent FLi4Tb square pyramids, and edges with four FLi3Tb trigonal pyramids. In the second F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Li1+more »
