Title: Materials Data on Li3W by Materials Project

Abstract

Li3W is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded to eight Li and four equivalent W atoms to form distorted LiLi8W4 cuboctahedra that share corners with twelve equivalent LiLi8W4 cuboctahedra, edges with eight equivalent LiLi8W4 cuboctahedra, edges with eight equivalent WLi12 cuboctahedra, faces with four equivalent WLi12 cuboctahedra, and faces with ten equivalent LiLi8W4 cuboctahedra. There are four shorter (2.70 Å) and four longer (2.91 Å) Li–Li bond lengths. All Li–W bond lengths are 2.91 Å. In the second Li site, Li is bonded in a square co-planar geometry to eight equivalent Li and four equivalent W atoms. All Li–W bond lengths are 2.70 Å. W is bonded to twelve Li atoms to form WLi12 cuboctahedra that share corners with four equivalent WLi12 cuboctahedra, edges with eight equivalent WLi12 cuboctahedra, edges with sixteen equivalent LiLi8W4 cuboctahedra, faces with four equivalent WLi12 cuboctahedra, and faces with eight equivalent LiLi8W4 cuboctahedra.
