SmCuCd crystallizes in the hexagonal P-62m space group. Sm(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Cd(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Cd(1) atoms. In the second Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Cd(1) atoms. Cd(1) is bonded in a 10-coordinate geometry to six equivalent Sm(1), two equivalent Cu(1), and two equivalent Cu(2) atoms.
SmCuCd crystallizes in the hexagonal P-62m space group. Sm(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Cd(1) atoms. The Sm(1)-Cu(2) bond length is 3.11 Å. All Sm(1)-Cu(1) bond lengths are 3.01 Å. There are two shorter (3.23 Å) and four longer (3.35 Å) Sm(1)-Cd(1) bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Cd(1) atoms. All Cu(2)-Cd(1) bond lengths are 2.72 Å. In the second Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Cd(1) atoms. All Cu(1)-Cd(1) bond lengths are 2.89 Å.
