The structure described by Lu4Ru7Ge6 crystallizes in the cubic Im-3m space group. Lu(1) is bonded to six equivalent Ru(2) and six equivalent Ge(1) atoms to form LuGe6Ru6 cuboctahedra that share corners with twelve equivalent Lu(1)Ge6Ru6 cuboctahedra, faces with six equivalent Lu(1)Ge6Ru6 cuboctahedra, and faces with two equivalent Ru(1)Ge6 octahedra. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to six equivalent Ge(1) atoms to form RuGe6 octahedra that share faces with eight equivalent Lu(1)Ge6Ru6 cuboctahedra. In the second Ru site, Ru(2) is bonded in a 8-coordinate geometry to four equivalent Lu(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Lu(1), one Ru(1), and four equivalent Ru(2) atoms. is represented by the CIF file [CIF]
