K2TbAuCl6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent Cl(1) atoms to form distorted KCl12 cuboctahedra that share corners with twelve equivalent K(1)Cl12 cuboctahedra, faces with six equivalent K(1)Cl12 cuboctahedra, faces with four equivalent Tb(1)Cl6 octahedra, and faces with four equivalent Au(1)Cl6 octahedra. Tb(1) is bonded to six equivalent Cl(1) atoms to form TbCl6 octahedra that share corners with six equivalent Au(1)Cl6 octahedra and faces with eight equivalent K(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Au(1) is bonded to six equivalent Cl(1) atoms to form AuCl6 octahedra that share corners with six equivalent Tb(1)Cl6 octahedra and faces with eight equivalent K(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a distorted linear geometry to four equivalent K(1), one Tb(1), and one Au(1) atom.
