Ho5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ho(1) and five equivalent Ho(2) atoms.
Ho5Pb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. All Ho(1)-Pb(1) bond lengths are 3.21 Å. In the second Ho site, Ho(2) is bonded in a 5-coordinate geometry to five equivalent Pb(1) atoms. There are a spread of Ho(2)-Pb(1) bond distances ranging from 3.07-3.58 Å. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Ho(1) and five equivalent Ho(2) atoms.
