Materials Data on LiCeSn by Materials Project
LiCeSn is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Li is bonded in a body-centered cubic geometry to four equivalent Ce and four equivalent Sn atoms. All Li–Ce bond lengths are 2.92 Å. All Li–Sn bond lengths are 2.92 Å. Ce is bonded in a distorted q6 geometry to four equivalent Li and six equivalent Sn atoms. All Ce–Sn bond lengths are 3.37 Å. Sn is bonded to four equivalent Li and six equivalent Ce atoms to form a mixture of distorted face and corner-sharing SnLi4Ce6 tetrahedra.
