Sm2Rh2Cd crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent Rh(1) and four equivalent Cd(1) atoms. Rh(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 Rh(1) atoms to form a mixture of distorted face and corner-sharing CdSm8Rh4 cuboctahedra.
Sm2Rh2Cd crystallizes in the tetragonal P4/mbm space group. Sm(1) is bonded in a 6-coordinate geometry to six equivalent Rh(1) and four equivalent Cd(1) atoms. There are two shorter (2.85 Å) and four longer (2.99 Å) Sm(1)-Rh(1) bond lengths. All Sm(1)-Cd(1) bond lengths are 3.40 Å. Rh(1) is bonded in a 8-coordinate geometry to six equivalent Sm(1) and two equivalent Cd(1) atoms. Both Rh(1)-Cd(1) bond lengths are 2.93 Å. Cd(1) is bonded to eight equivalent Sm(1) and four equivalent Rh(1) atoms to form a mixture of distorted face and corner-sharing CdSm8Rh4 cuboctahedra.
