Yb4Rh7Sb6 crystallizes in the cubic Im-3m space group. Yb(1) is bonded to six equivalent Rh(1) and six equivalent Sb(1) atoms to form YbSb6Rh6 cuboctahedra that share corners with twelve equivalent Yb(1)Sb6Rh6 cuboctahedra, faces with six equivalent Yb(1)Sb6Rh6 cuboctahedra, and faces with two equivalent Rh(2)Sb6 octahedra. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to four equivalent Yb(1) and four equivalent Sb(1) atoms. In the second Rh site, Rh(2) is bonded to six equivalent Sb(1) atoms to form RhSb6 octahedra that share faces with eight equivalent Yb(1)Sb6Rh6 cuboctahedra. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), one Rh(2), and four equivalent Rh(1) atoms.
