Sm2Cu2Cd crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent Cd(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), one Cu(1), and two equivalent Cd(1) atoms. Cd(1) is bonded to eight equivalent Sm(1) and four equivalent Cu(1) atoms to form a mixture of face and corner-sharing CdSm8Cu4 cuboctahedra.
Sm2Cu2Cd crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 10-coordinate geometry to six equivalent Cu(1) and four equivalent Cd(1) atoms. There are two shorter (2.92 Å) and four longer (2.97 Å) Sm(1)-Cu(1) bond lengths. All Sm(1)-Cd(1) bond lengths are 3.39 Å. Cu(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1), one Cu(1), and two equivalent Cd(1) atoms. The Cu(1)-Cu(1) bond length is 2.55 Å. Both Cu(1)-Cd(1) bond lengths are 3.03 Å. Cd(1) is bonded to eight equivalent Sm(1) and four equivalent Cu(1) atoms to form a mixture of face and corner-sharing CdSm8Cu4 cuboctahedra.
