Dy(RhZn10)2 crystallizes in the cubic Fd-3m space group. Dy(1) is bonded in a 16-coordinate geometry to four equivalent Zn(2) and twelve equivalent Zn(1) atoms. Rh(1) is bonded to six equivalent Zn(1) and six equivalent Zn(3) atoms to form corner-sharing RhZn12 cuboctahedra. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to one Dy(1), one Rh(1), two equivalent Zn(2), three equivalent Zn(3), and five equivalent Zn(1) atoms. In the second Zn site, Zn(2) is bonded in a distorted linear geometry to two equivalent Dy(1) and twelve equivalent Zn(1) atoms. In the third Zn site, Zn(3) is bonded in a distorted linear geometry to two equivalent Rh(1) and six equivalent Zn(1) atoms.
Dy(RhZn10)2 crystallizes in the cubic Fd-3m space group. Dy(1) is bonded in a 16-coordinate geometry to four equivalent Zn(2) and twelve equivalent Zn(1) atoms. All Dy(1)-Zn(2) bond lengths are 3.14 Å. All Dy(1)-Zn(1) bond lengths are 3.17 Å. Rh(1) is bonded to six equivalent Zn(1) and six equivalent Zn(3) atoms to form corner-sharing RhZn12 cuboctahedra. All Rh(1)-Zn(1) bond lengths are 2.83 Å. All Rh(1)-Zn(3) bond lengths are 2.57 Å. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to one Dy(1), one Rh(1), two equivalent Zn(2), three equivalent Zn(3), and five equivalent Zn(1) atoms.
