The crystal structure described by K2TbAgCl6 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 Ag(1)Cl6 octahedra. Tb(1) is bonded to six equivalent Cl(1) atoms to form TbCl6 octahedra that share corners with six equivalent Ag(1)Cl6 octahedra and faces with eight equivalent K(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Ag(1) is bonded to six equivalent Cl(1) atoms to form AgCl6 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 linear geometry to four equivalent K(1), one Tb(1), and one Ag(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
