The compound described by Li15Ge4 crystallizes in the cubic I-43d space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 3-coordinate geometry to two equivalent Li(2) and three equivalent Ge(1) atoms. In the second Li site, Li(2) is bonded to eight equivalent Li(1) and four equivalent Ge(1) atoms to form LiLi8Ge4 cuboctahedra that share corners with eight equivalent Ge(1)Li12 cuboctahedra, edges with eight equivalent Li(2)Li8Ge4 cuboctahedra, and faces with four equivalent Ge(1)Li12 cuboctahedra. Ge(1) is bonded to three equivalent Li(2) and nine equivalent Li(1) atoms to form distorted GeLi12 cuboctahedra that share corners with six equivalent Li(2)Li8Ge4 cuboctahedra, edges with six equivalent Ge(1)Li12 cuboctahedra, faces with three equivalent Li(2)Li8Ge4 cuboctahedra, and faces with five equivalent Ge(1)Li12 cuboctahedra. is represented by the CIF card [CIF]
