Rb2NdAgF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form RbF12 cuboctahedra that share corners with twelve equivalent Rb(1)F12 cuboctahedra, faces with six equivalent Rb(1)F12 cuboctahedra, faces with four equivalent Nd(1)F6 octahedra, and faces with four equivalent Ag(1)F6 octahedra. Nd(1) is bonded to six equivalent F(1) atoms to form NdF6 octahedra that share corners with six equivalent Ag(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Ag(1) is bonded to six equivalent F(1) atoms to form AgF6 octahedra that share corners with six equivalent Nd(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent Rb(1), one Nd(1), and one Ag(1) atom.
