Yb4Rh7Ge6 crystallizes in the cubic Im-3m space group. Yb(1) is bonded to six equivalent Rh(1) and six equivalent Ge(1) atoms to form YbGe6Rh6 cuboctahedra that share corners with twelve equivalent Yb(1)Ge6Rh6 cuboctahedra, faces with six equivalent Yb(1)Ge6Rh6 cuboctahedra, and faces with two equivalent Rh(2)Ge6 octahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded to six equivalent Ge(1) atoms to form RhGe6 octahedra that share faces with eight equivalent Yb(1)Ge6Rh6 cuboctahedra. In the second Rh site, Rh(1) is bonded in a 8-coordinate geometry to four equivalent Yb(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Rh(2), and four equivalent Rh(1) atoms.
