BaSm3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ba(1) is bonded to twelve equivalent Sm(1) atoms to form BaSm12 cuboctahedra that share corners with twelve equivalent Ba(1)Sm12 cuboctahedra, edges with twenty-four equivalent Sm(1)Ba4Sm8 cuboctahedra, faces with six equivalent Ba(1)Sm12 cuboctahedra, and faces with twelve equivalent Sm(1)Ba4Sm8 cuboctahedra. Sm(1) is bonded to four equivalent Ba(1) and eight equivalent Sm(1) atoms to form SmBa4Sm8 cuboctahedra that share corners with twelve equivalent Sm(1)Ba4Sm8 cuboctahedra, edges with eight equivalent Ba(1)Sm12 cuboctahedra, edges with sixteen equivalent Sm(1)Ba4Sm8 cuboctahedra, faces with four equivalent Ba(1)Sm12 cuboctahedra, and faces with fourteen equivalent Sm(1)Ba4Sm8 cuboctahedra.
