DySm3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Dy(1) is bonded to twelve equivalent Sm(1) atoms to form DySm12 cuboctahedra that share corners with six equivalent Dy(1)Sm12 cuboctahedra, corners with twelve equivalent Sm(1)Sm8Dy4 cuboctahedra, edges with eighteen equivalent Sm(1)Sm8Dy4 cuboctahedra, faces with eight equivalent Dy(1)Sm12 cuboctahedra, and faces with twelve equivalent Sm(1)Sm8Dy4 cuboctahedra. Sm(1) is bonded to four equivalent Dy(1) and eight equivalent Sm(1) atoms to form SmSm8Dy4 cuboctahedra that share corners with four equivalent Dy(1)Sm12 cuboctahedra, corners with fourteen equivalent Sm(1)Sm8Dy4 cuboctahedra, edges with six equivalent Dy(1)Sm12 cuboctahedra, edges with twelve equivalent Sm(1)Sm8Dy4 cuboctahedra, faces with four equivalent Dy(1)Sm12 cuboctahedra, and faces with sixteen equivalent Sm(1)Sm8Dy4 cuboctahedra.
