The structure described by K2TbCuCl6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent Cl(1) atoms to form 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 Cu(1)Cl6 octahedra. Tb(1) is bonded to six equivalent Cl(1) atoms to form TbCl6 octahedra that share corners with six equivalent Cu(1)Cl6 octahedra and faces with eight equivalent K(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cu(1) is bonded to six equivalent Cl(1) atoms to form CuCl6 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 Cu(1) atom. is represented by the CIF file [CIF]
