TbIn3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Tb(1) is bonded to twelve equivalent In(1) atoms to form TbIn12 cuboctahedra that share corners with twelve equivalent Tb(1)In12 cuboctahedra, edges with twenty-four equivalent In(1)Tb4In8 cuboctahedra, faces with six equivalent Tb(1)In12 cuboctahedra, and faces with twelve equivalent In(1)Tb4In8 cuboctahedra. In(1) is bonded to four equivalent Tb(1) and eight equivalent In(1) atoms to form distorted InTb4In8 cuboctahedra that share corners with twelve equivalent In(1)Tb4In8 cuboctahedra, edges with eight equivalent Tb(1)In12 cuboctahedra, edges with sixteen equivalent In(1)Tb4In8 cuboctahedra, faces with four equivalent Tb(1)In12 cuboctahedra, and faces with fourteen equivalent In(1)Tb4In8 cuboctahedra.
