Li2PtSb is Zintl Phase-derived structured and crystallizes in the cubic F-43m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to four equivalent Pt(1) and six equivalent Sb(1) atoms to form distorted LiSb6Pt4 tetrahedra that share corners with six equivalent Li(1)Sb6Pt4 tetrahedra, edges with twelve equivalent Li(2)Sb4Pt6 tetrahedra, faces with four equivalent Li(2)Sb4Pt6 tetrahedra, and faces with twelve equivalent Li(1)Sb6Pt4 tetrahedra. In the second Li site, Li(2) is bonded to six equivalent Pt(1) and four equivalent Sb(1) atoms to form distorted LiSb4Pt6 tetrahedra that share corners with six equivalent Li(2)Sb4Pt6 tetrahedra, edges with twelve equivalent Li(1)Sb6Pt4 tetrahedra, faces with four equivalent Li(1)Sb6Pt4 tetrahedra, and faces with twelve equivalent Li(2)Sb4Pt6 tetrahedra. Pt(1) is bonded in a 14-coordinate geometry to four equivalent Li(1), six equivalent Li(2), and four equivalent Sb(1) atoms. Sb(1) is bonded in a 14-coordinate geometry to four equivalent Li(2), six equivalent Li(1), and four equivalent Pt(1) atoms.
