Li2PdGe is Zintl Phase-derived structured and 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 Pd and six equivalent Ge atoms to form distorted LiGe6Pd4 tetrahedra that share corners with six equivalent LiGe6Pd4 tetrahedra, edges with twelve equivalent LiGe4Pd6 tetrahedra, and faces with sixteen LiGe6Pd4 tetrahedra. All Li–Pd bond lengths are 2.63 Å. All Li–Ge bond lengths are 3.04 Å. In the second Li site, Li is bonded to six equivalent Pd and four equivalent Ge atoms to form distorted LiGe4Pd6 tetrahedra that share corners with six equivalent LiGe4Pd6 tetrahedra, edges with twelve equivalent LiGe6Pd4 tetrahedra, and faces with sixteen LiGe6Pd4 tetrahedra. All Li–Pd bond lengths are 3.04 Å. All Li–Ge bond lengths are 2.63 Å. Pd is bonded in a 8-coordinate geometry to ten Li and four equivalent Ge atoms. All Pd–Ge bond lengths are 2.63 Å. Ge is bonded in a 8-coordinate geometry to ten Li and four equivalent Pd atoms.
