Materials Data on RbCuPdF5 by Materials Project

RbPdCuF5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rb1+ is bonded in a 11-coordinate geometry to eleven F1- atoms. There are a spread of Rb–F bond distances ranging from 2.87–3.34 Å. Pd2+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. There are two shorter (1.99 Å) and two longer (2.01 Å) Pd–F bond lengths. Cu2+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are a spread of Cu–F bond distances ranging from 1.98–2.19 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Pd2+, and one Cu2+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Pd2+, and one Cu2+ atom. In the third F1- site, F1- is bonded in a distorted bent 150 degrees geometry to three equivalent Rb1+ and two equivalent Cu2+ atoms.

Materials Data on Rb2CuPdF6 by Materials Project

Rb2PdCuF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb1+ is bonded to twelve equivalent F1- atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, faces with four equivalent PdF6 octahedra, and faces with four equivalent CuF6 octahedra. All Rb–F bond lengths are 3.00 Å. Pd2+ is bonded to six equivalent F1- atoms to form PdF6 octahedra that share corners with six equivalent CuF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Pd–F bond lengths are 2.18 Å. Cu2+ is bonded to six equivalent F1- atoms to form CuF6 octahedra that share corners with six equivalent PdF6 octahedra and faces with eight equivalent RbF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cu–F bond lengths are 2.07 Å. F1- is bonded in a distorted linear geometry to four equivalent Rb1+, one Pd2+, and one Cu2+ atom.
