YTb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tb(1) is bonded to eight equivalent Tb(1) and four equivalent Y(1) atoms to form TbTb8Y4 cuboctahedra that share corners with twelve equivalent Tb(1)Tb8Y4 cuboctahedra, edges with eight equivalent Y(1)Tb12 cuboctahedra, edges with sixteen equivalent Tb(1)Tb8Y4 cuboctahedra, faces with four equivalent Y(1)Tb12 cuboctahedra, and faces with fourteen equivalent Tb(1)Tb8Y4 cuboctahedra. Y(1) is bonded to twelve equivalent Tb(1) atoms to form YTb12 cuboctahedra that share corners with twelve equivalent Y(1)Tb12 cuboctahedra, edges with twenty-four equivalent Tb(1)Tb8Y4 cuboctahedra, faces with six equivalent Y(1)Tb12 cuboctahedra, and faces with twelve equivalent Tb(1)Tb8Y4 cuboctahedra.
