LiAlGe is half-Heusler structured and crystallizes in the cubic F-43m space group. Li(1) is bonded in a body-centered cubic geometry to four equivalent Al(1) and four equivalent Ge(1) atoms. Al(1) is bonded to four equivalent Li(1) and six equivalent Ge(1) atoms to form distorted AlLi4Ge6 tetrahedra that share corners with four equivalent Ge(1)Li4Al6 tetrahedra, corners with six equivalent Al(1)Li4Ge6 tetrahedra, edges with six equivalent Ge(1)Li4Al6 tetrahedra, and faces with twelve equivalent Al(1)Li4Ge6 tetrahedra. Ge(1) is bonded to four equivalent Li(1) and six equivalent Al(1) atoms to form distorted GeLi4Al6 tetrahedra that share corners with four equivalent Al(1)Li4Ge6 tetrahedra, corners with six equivalent Ge(1)Li4Al6 tetrahedra, edges with six equivalent Al(1)Li4Ge6 tetrahedra, and faces with twelve equivalent Ge(1)Li4Al6 tetrahedra.
