The material described by TbEu3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded to twelve equivalent Eu(1) atoms to form TbEu12 cuboctahedra that share corners with six equivalent Tb(1)Eu12 cuboctahedra, corners with twelve equivalent Eu(1)Tb4Eu8 cuboctahedra, edges with eighteen equivalent Eu(1)Tb4Eu8 cuboctahedra, faces with eight equivalent Tb(1)Eu12 cuboctahedra, and faces with twelve equivalent Eu(1)Tb4Eu8 cuboctahedra. Eu(1) is bonded to four equivalent Tb(1) and eight equivalent Eu(1) atoms to form EuTb4Eu8 cuboctahedra that share corners with four equivalent Tb(1)Eu12 cuboctahedra, corners with fourteen equivalent Eu(1)Tb4Eu8 cuboctahedra, edges with six equivalent Tb(1)Eu12 cuboctahedra, edges with twelve equivalent Eu(1)Tb4Eu8 cuboctahedra, faces with four equivalent Tb(1)Eu12 cuboctahedra, and faces with sixteen equivalent Eu(1)Tb4Eu8 cuboctahedra. is represented by the CIF file [CIF]
