The crystal structure described by Li8Nd7Ge10 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one Nd(1), two equivalent Nd(3), one Ge(2), one Ge(4), and two equivalent Ge(3) atoms to form distorted LiNd3Ge4 tetrahedra that share corners with five equivalent Li(1)Nd3Ge4 tetrahedra, edges with two equivalent Nd(4)Ge6 octahedra, edges with two equivalent Li(1)Nd3Ge4 tetrahedra, edges with four equivalent Li(2)Nd3Ge4 tetrahedra, faces with two equivalent Li(1)Nd3Ge4 tetrahedra, and faces with two equivalent Li(2)Nd3Ge4 tetrahedra. In the second Li site, Li(2) is bonded to one Nd(3), two equivalent Nd(1), one Ge(1), one Ge(3), and two equivalent Ge(2) atoms to form distorted LiNd3Ge4 tetrahedra that share  a cornercorner with one Nd(4)Ge6 octahedra, corners with four equivalent Li(2)Nd3Ge4 tetrahedra, edges with two equivalent Li(2)Nd3Ge4 tetrahedra, edges with four equivalent Li(1)Nd3Ge4 tetrahedra, faces with two equivalent Li(1)Nd3Ge4 tetrahedra, and faces with two equivalent Li(2)Nd3Ge4 tetrahedra. The corner-sharing octahedral tilt angles are 52°. There are four inequivalent Nd sites. In the first Nd site, Nd(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 Nd site, Nd(2) is bonded in a 9-coordinate geometry to one Ge(2) and eight equivalent Ge(1) atoms. In the third Nd site, Nd(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 Nd site, Nd(4) is bonded to two equivalent Ge(3) and four equivalent Ge(4) atoms to form NdGe6 octahedra that share corners with four equivalent Li(2)Nd3Ge4 tetrahedra, edges with two equivalent Nd(4)Ge6 octahedra, and edges with eight equivalent Li(1)Nd3Ge4 tetrahedra. There are four inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Li(1), four equivalent Li(2), one Nd(2), and two equivalent Nd(3) atoms.
