Dy5NiPb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 7-coordinate geometry to two equivalent Ni(1) and five equivalent Pb(1) atoms. In the second Dy site, Dy(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. Ni(1) is bonded to six equivalent Dy(1) atoms to form face-sharing NiDy6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Dy(2) and five equivalent Dy(1) atoms.
Dy5NiPb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 7-coordinate geometry to two equivalent Ni(1) and five equivalent Pb(1) atoms. Both Dy(1)-Ni(1) bond lengths are 2.74 Å. There are a spread of Dy(1)-Pb(1) bond distances ranging from 3.16-3.66 Å. In the second Dy site, Dy(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All Dy(2)-Pb(1) bond lengths are 3.24 Å. Ni(1) is bonded to six equivalent Dy(1) atoms to form face-sharing NiDy6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Dy(2) and five equivalent Dy(1) atoms.
