In the third Ho site, Ho(3) is bonded to four equivalent Rh(1), two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms to form face-sharing HoGe8Rh4 cuboctahedra. Rh(1) is bonded in a 10-coordinate geometry to one Ho(1), two equivalent Ho(2), two equivalent Ho(3), one Ge(1), two equivalent Ge(2), and two equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ho(3), four equivalent Ho(2), two equivalent Rh(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 2-coordinate geometry to one Ho(1), two equivalent Ho(2), two equivalent Ho(3), and two equivalent Rh(1) atoms. In the third Ge site, Ge(3) is bonded in a 2-coordinate geometry to one Ho(2), one Ho(3), two equivalent Ho(1), and two equivalent Rh(1) atoms.
