The compound described by Tb3Ce is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded to eight equivalent Tb(1) and four equivalent Ce(1) atoms to form TbTb8Ce4 cuboctahedra that share corners with four equivalent Ce(1)Tb12 cuboctahedra, corners with fourteen equivalent Tb(1)Tb8Ce4 cuboctahedra, edges with six equivalent Ce(1)Tb12 cuboctahedra, edges with twelve equivalent Tb(1)Tb8Ce4 cuboctahedra, faces with four equivalent Ce(1)Tb12 cuboctahedra, and faces with sixteen equivalent Tb(1)Tb8Ce4 cuboctahedra. Ce(1) is bonded to twelve equivalent Tb(1) atoms to form CeTb12 cuboctahedra that share corners with six equivalent Ce(1)Tb12 cuboctahedra, corners with twelve equivalent Tb(1)Tb8Ce4 cuboctahedra, edges with eighteen equivalent Tb(1)Tb8Ce4 cuboctahedra, faces with eight equivalent Ce(1)Tb12 cuboctahedra, and faces with twelve equivalent Tb(1)Tb8Ce4 cuboctahedra. is represented by the CIF file [CIF]
