Pb is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to six equivalent Pb(1) and six equivalent Pb(2) atoms to form a mixture of corner, edge, and face-sharing PbPb12 cuboctahedra. In the second Pb site, Pb(2) is bonded to six equivalent Pb(1) and six equivalent Pb(2) atoms to form a mixture of corner, edge, and face-sharing PbPb12 cuboctahedra.

In the first Pb site, Pb(1) is bonded to six equivalent Pb(1) and six equivalent Pb(2) atoms to form a mixture of corner, edge, and face-sharing PbPb12 cuboctahedra. All Pb(1)-Pb(1) bond lengths are 3.52 Å. All Pb(1)-Pb(2) bond lengths are 3.52 Å. In the second Pb site, Pb(2) is bonded to six equivalent Pb(1) and six equivalent Pb(2) atoms to form a mixture of corner, edge, and face-sharing PbPb12 cuboctahedra. All Pb(2)-Pb(2) bond lengths are 3.52 Å.
