The material structure described by Tm3Sm is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tm(1) is bonded to eight equivalent Tm(1) and four equivalent Sm(1) atoms to form TmSm4Tm8 cuboctahedra that share corners with twelve equivalent Tm(1)Sm4Tm8 cuboctahedra, edges with eight equivalent Sm(1)Tm12 cuboctahedra, edges with sixteen equivalent Tm(1)Sm4Tm8 cuboctahedra, faces with four equivalent Sm(1)Tm12 cuboctahedra, and faces with fourteen equivalent Tm(1)Sm4Tm8 cuboctahedra. Sm(1) is bonded to twelve equivalent Tm(1) atoms to form SmTm12 cuboctahedra that share corners with twelve equivalent Sm(1)Tm12 cuboctahedra, edges with twenty-four equivalent Tm(1)Sm4Tm8 cuboctahedra, faces with six equivalent Sm(1)Tm12 cuboctahedra, and faces with twelve equivalent Tm(1)Sm4Tm8 cuboctahedra. is represented by the CIF card [CIF]
