The crystal structure described by Li8Ce7Ge10 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one Ce(1), two equivalent Ce(3), one Ge(2), one Ge(4), and two equivalent Ge(3) atoms to form distorted LiCe3Ge4 tetrahedra that share corners with five equivalent Li(1)Ce3Ge4 tetrahedra, edges with two equivalent Ce(4)Ge6 octahedra, edges with two equivalent Li(1)Ce3Ge4 tetrahedra, edges with four equivalent Li(2)Ce3Ge4 tetrahedra, faces with two equivalent Li(1)Ce3Ge4 tetrahedra, and faces with two equivalent Li(2)Ce3Ge4 tetrahedra. In the second Li site, Li(2) is bonded to one Ce(3), two equivalent Ce(1), one Ge(1), one Ge(3), and two equivalent Ge(2) atoms to form distorted LiCe3Ge4 tetrahedra that share  a cornercorner with one Ce(4)Ge6 octahedra, corners with four equivalent Li(2)Ce3Ge4 tetrahedra, edges with two equivalent Li(2)Ce3Ge4 tetrahedra, edges with four equivalent Li(1)Ce3Ge4 tetrahedra, faces with two equivalent Li(1)Ce3Ge4 tetrahedra, and faces with two equivalent Li(2)Ce3Ge4 tetrahedra. The corner-sharing octahedral tilt angles are 53°. There are four inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 12-coordinate geometry to two equivalent Li(1), four equivalent Li(2), two equivalent Ge(3), and four equivalent Ge(1) atoms. In the second Ce site, Ce(2) is bonded in a 9-coordinate geometry to one Ge(2) and eight equivalent Ge(1) atoms. In the third Ce site, Ce(3) is bonded in a 12-coordinate geometry to two equivalent Li(2), four equivalent Li(1), two equivalent Ge(2), and four equivalent Ge(4) atoms. In the fourth Ce site, Ce(4) is bonded to two equivalent Ge(3) and four equivalent Ge(4) atoms to form CeGe6 octahedra that share corners with four equivalent Li(2)Ce3Ge4 tetrahedra, edges with two equivalent Ce(4)Ge6 octahedra, and edges with eight equivalent Li(1)Ce3Ge4 tetrahedra. There are four inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 6-coordinate geometry to two equivalent Li(1), four equivalent Li(2), one Ce(2), and two equivalent Ce(3) atoms. In the second Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Li(2), four equivalent Li(1), one Ce(4), and two equivalent Ce(1) atoms. In the third Ge site, Ge(4) is bonded in a 9-coordinate geometry to two equivalent Li(1), two equivalent Ce(4), four equivalent Ce(3), and one Ge(4) atom.
