Lu5NiPb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 7-coordinate geometry to two equivalent Ni(1) and five equivalent Pb(1) atoms. In the second Lu site, Lu(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. Ni(1) is bonded to six equivalent Lu(1) atoms to form face-sharing NiLu6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Lu(2) and five equivalent Lu(1) atoms.
Lu5NiPb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 7-coordinate geometry to two equivalent Ni(1) and five equivalent Pb(1) atoms. Both Lu(1)-Ni(1) bond lengths are 2.66 Å. There are a spread of Lu(1)-Pb(1) bond distances ranging from 3.10-3.58 Å. In the second Lu site, Lu(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All Lu(2)-Pb(1) bond lengths are 3.17 Å. Ni(1) is bonded to six equivalent Lu(1) atoms to form face-sharing NiLu6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Lu(2) and five equivalent Lu(1) atoms.
