HoTb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ho(1) is bonded to twelve equivalent Tb(1) atoms to form HoTb12 cuboctahedra that share corners with twelve equivalent Ho(1)Tb12 cuboctahedra, edges with twenty-four equivalent Tb(1)Tb8Ho4 cuboctahedra, faces with six equivalent Ho(1)Tb12 cuboctahedra, and faces with twelve equivalent Tb(1)Tb8Ho4 cuboctahedra. Tb(1) is bonded to four equivalent Ho(1) and eight equivalent Tb(1) atoms to form TbTb8Ho4 cuboctahedra that share corners with twelve equivalent Tb(1)Tb8Ho4 cuboctahedra, edges with eight equivalent Ho(1)Tb12 cuboctahedra, edges with sixteen equivalent Tb(1)Tb8Ho4 cuboctahedra, faces with four equivalent Ho(1)Tb12 cuboctahedra, and faces with fourteen equivalent Tb(1)Tb8Ho4 cuboctahedra.
