The compound described by Sm3Cd is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded to eight equivalent Sm(1) and four equivalent Cd(1) atoms to form distorted SmSm8Cd4 cuboctahedra that share corners with four equivalent Cd(1)Sm12 cuboctahedra, corners with fourteen equivalent Sm(1)Sm8Cd4 cuboctahedra, edges with six equivalent Cd(1)Sm12 cuboctahedra, edges with twelve equivalent Sm(1)Sm8Cd4 cuboctahedra, faces with four equivalent Cd(1)Sm12 cuboctahedra, and faces with sixteen equivalent Sm(1)Sm8Cd4 cuboctahedra. Cd(1) is bonded to twelve equivalent Sm(1) atoms to form CdSm12 cuboctahedra that share corners with six equivalent Cd(1)Sm12 cuboctahedra, corners with twelve equivalent Sm(1)Sm8Cd4 cuboctahedra, edges with eighteen equivalent Sm(1)Sm8Cd4 cuboctahedra, faces with eight equivalent Cd(1)Sm12 cuboctahedra, and faces with twelve equivalent Sm(1)Sm8Cd4 cuboctahedra. is represented by the CIF card [CIF]
