Materials Data on Li2SnPt by Materials Project

Abstract

Li2PtSn crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded to four equivalent Pt atoms to form distorted LiPt4 tetrahedra that share corners with twenty-four LiPt4 tetrahedra and faces with four equivalent LiSn4Pt6 tetrahedra. All Li–Pt bond lengths are 2.76 Å. In the second Li site, Li is bonded to six equivalent Pt and four equivalent Sn atoms to form distorted LiSn4Pt6 tetrahedra that share corners with eighteen LiPt4 tetrahedra and faces with sixteen LiSn4Pt6 tetrahedra. All Li–Pt bond lengths are 3.18 Å. All Li–Sn bond lengths are 2.76 Å. Pt is bonded in a 8-coordinate geometry to ten Li and four equivalent Sn atoms. All Pt–Sn bond lengths are 2.76 Å. Sn is bonded in a distorted body-centered cubic geometry to four equivalent Li and four equivalent Pt atoms.
