SmPdHg crystallizes in the hexagonal P-62m space group. Sm(1) is bonded in a 11-coordinate geometry to one Pd(1), four equivalent Pd(2), and six equivalent Hg(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Hg(1) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Hg(1) atoms. Hg(1) is bonded in a distorted q6 geometry to six equivalent Sm(1), two equivalent Pd(1), and two equivalent Pd(2) atoms.
SmPdHg crystallizes in the hexagonal P-62m space group. Sm(1) is bonded in a 11-coordinate geometry to one Pd(1), four equivalent Pd(2), and six equivalent Hg(1) atoms. The Sm(1)-Pd(1) bond length is 3.08 Å. All Sm(1)-Pd(2) bond lengths are 3.06 Å. There are two shorter (3.23 Å) and four longer (3.33 Å) Sm(1)-Hg(1) bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Hg(1) atoms. All Pd(1)-Hg(1) bond lengths are 2.83 Å. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Hg(1) atoms. All Pd(2)-Hg(1) bond lengths are 2.87 Å. Hg(1) is bonded in a distorted q6 geometry to six equivalent Sm(1), two equivalent Pd(1), and two equivalent Pd(2) atoms.
