LuTb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Lu(1) is bonded to twelve equivalent Tb(1) atoms to form LuTb12 cuboctahedra that share corners with twelve equivalent Lu(1)Tb12 cuboctahedra, edges with twenty-four equivalent Tb(1)Tb8Lu4 cuboctahedra, faces with six equivalent Lu(1)Tb12 cuboctahedra, and faces with twelve equivalent Tb(1)Tb8Lu4 cuboctahedra. Tb(1) is bonded to four equivalent Lu(1) and eight equivalent Tb(1) atoms to form TbTb8Lu4 cuboctahedra that share corners with twelve equivalent Tb(1)Tb8Lu4 cuboctahedra, edges with eight equivalent Lu(1)Tb12 cuboctahedra, edges with sixteen equivalent Tb(1)Tb8Lu4 cuboctahedra, faces with four equivalent Lu(1)Tb12 cuboctahedra, and faces with fourteen equivalent Tb(1)Tb8Lu4 cuboctahedra.
