SmPdPb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-62m space group. Sm(1) is bonded to two equivalent Pd(2), four equivalent Pd(1), and six equivalent Pb(1) atoms to form a mixture of edge and face-sharing SmPd6Pb6 cuboctahedra. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Pb(1) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Pb(1) atoms. Pb(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), one Pd(2), and two equivalent Pd(1) atoms.

Sm(1) is bonded to two equivalent Pd(2), four equivalent Pd(1), and six equivalent Pb(1) atoms to form a mixture of edge and face-sharing SmPd6Pb6 cuboctahedra. Both Sm(1)-Pd(2) bond lengths are 3.34 Å. All Sm(1)-Pd(1) bond lengths are 3.35 Å. There are four shorter (3.34 Å) and two longer (3.35 Å) Sm(1)-Pb(1) bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Pb(1) atoms. All Pd(1)-Pb(1) bond lengths are 2.75 Å. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Pb(1) atoms. All Pd(2)-Pb(1) bond lengths are 2.74 Å. Pb(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), one Pd(2), and two equivalent Pd(1) atoms.
