Materials Data on KPd2F5 by Materials Project
KPd2F5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of K–F bond distances ranging from 2.78–2.98 Å. There are two inequivalent Pd2+ sites. In the first Pd2+ site, Pd2+ is bonded to six F1- atoms to form corner-sharing PdF6 octahedra. The corner-sharing octahedral tilt angles are 60°. There are a spread of Pd–F bond distances ranging from 2.19–2.22 Å. In the second Pd2+ site, Pd2+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. All Pd–F bond lengths are 2.01 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to one K1+ and two Pd2+ atoms. In the second F1- site, F1- is bonded in a 4-coordinate geometry to two equivalent K1+ and two Pd2+ atoms. In the third F1- site, F1- is bonded in a 4-coordinate geometry to two equivalent K1+ and two equivalent Pd2+ atoms.
