The structure described by Cs2CeAgCl6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent Cl(1) atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent Cs(1)Cl12 cuboctahedra, faces with six equivalent Cs(1)Cl12 cuboctahedra, faces with four equivalent Ce(1)Cl6 octahedra, and faces with four equivalent Ag(1)Cl6 octahedra. Ce(1) is bonded to six equivalent Cl(1) atoms to form CeCl6 octahedra that share corners with six equivalent Ag(1)Cl6 octahedra and faces with eight equivalent Cs(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 Ce(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded to four equivalent Cs(1), one Ce(1), and one Ag(1) atom to form a mixture of distorted edge, corner, and face-sharing ClCs4CeAg octahedra. The corner-sharing octahedral tilt angles range from 0-60°. is represented by the Crystallographic Information File (CIF) [CIF]
