EuSm3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Eu(1) is bonded to twelve equivalent Sm(1) atoms to form EuSm12 cuboctahedra that share corners with twelve equivalent Eu(1)Sm12 cuboctahedra, edges with twenty-four equivalent Sm(1)Sm8Eu4 cuboctahedra, faces with six equivalent Eu(1)Sm12 cuboctahedra, and faces with twelve equivalent Sm(1)Sm8Eu4 cuboctahedra. Sm(1) is bonded to four equivalent Eu(1) and eight equivalent Sm(1) atoms to form SmSm8Eu4 cuboctahedra that share corners with twelve equivalent Sm(1)Sm8Eu4 cuboctahedra, edges with eight equivalent Eu(1)Sm12 cuboctahedra, edges with sixteen equivalent Sm(1)Sm8Eu4 cuboctahedra, faces with four equivalent Eu(1)Sm12 cuboctahedra, and faces with fourteen equivalent Sm(1)Sm8Eu4 cuboctahedra.
