Sm2Au2Cd crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Cd(1) atoms. Au(1) is bonded in a 8-coordinate geometry to six equivalent Sm(1) and two equivalent Cd(1) atoms. Cd(1) is bonded to eight equivalent Sm(1) and four equivalent Au(1) atoms to form a mixture of distorted corner and face-sharing CdSm8Au4 cuboctahedra.
Sm2Au2Cd crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) and four equivalent Cd(1) atoms. There are two shorter (2.96 Å) and four longer (3.08 Å) Sm(1)-Au(1) bond lengths. All Sm(1)-Cd(1) bond lengths are 3.53 Å. Au(1) is bonded in a 8-coordinate geometry to six equivalent Sm(1) and two equivalent Cd(1) atoms. Both Au(1)-Cd(1) bond lengths are 3.15 Å. Cd(1) is bonded to eight equivalent Sm(1) and four equivalent Au(1) atoms to form a mixture of distorted corner and face-sharing CdSm8Au4 cuboctahedra.
