Rb2NaPdF6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded to four equivalent F(2) and eight 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 Na(1)F6 octahedra, and faces with four equivalent Pd(1)F6 octahedra. Na(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form NaF6 octahedra that share corners with six equivalent Pd(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Pd(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form PdF6 octahedra that share corners with six equivalent Na(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to four equivalent Rb(1), one Na(1), and one Pd(1) atom. In the second F site, F(2) is bonded to four equivalent Rb(1), one Na(1), and one Pd(1) atom to form a mixture of distorted corner and edge-sharing FRb4NaPd octahedra. The corner-sharing octahedral tilt angles range from 0-1°.
