Materials Data on Li3Ge by Materials Project

Abstract

Li3Ge is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded to four equivalent Li and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing LiLi4Ge4 tetrahedra. All Li–Li bond lengths are 2.70 Å. All Li–Ge bond lengths are 2.70 Å. In the second Li site, Li is bonded in a 8-coordinate geometry to eight equivalent Li and six equivalent Ge atoms. All Li–Ge bond lengths are 3.11 Å. Ge is bonded in a body-centered cubic geometry to fourteen Li atoms.
