SmPdPb crystallizes in the hexagonal P-62m space group. Sm(1) is bonded in a 11-coordinate geometry to one Pd(2), four equivalent Pd(1), and six equivalent Pb(1) atoms. 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 three equivalent Sm(1) and six equivalent Pb(1) atoms. Pb(1) is bonded in a 10-coordinate geometry to six equivalent Sm(1), two equivalent Pd(1), and two equivalent Pd(2) atoms.
SmPdPb crystallizes in the hexagonal P-62m space group. Sm(1) is bonded in a 11-coordinate geometry to one Pd(2), four equivalent Pd(1), and six equivalent Pb(1) atoms. The Sm(1)-Pd(2) bond length is 3.15 Å. All Sm(1)-Pd(1) bond lengths are 3.11 Å. There are two shorter (3.29 Å) and four longer (3.43 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 2.91 Å. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Pb(1) atoms. All Pd(2)-Pb(1) bond lengths are 2.86 Å. Pb(1) is bonded in a 10-coordinate geometry to six equivalent Sm(1), two equivalent Pd(1), and two equivalent Pd(2) atoms.
