Materials Data on K2RbPdF5 by Materials Project
RbK2PdF5 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Rb1+ is bonded in a distorted q6 geometry to ten F1- atoms. There are two shorter (3.18 Å) and eight longer (3.19 Å) Rb–F bond lengths. K1+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of K–F bond distances ranging from 2.64–2.91 Å. Pd2+ is bonded in a square co-planar geometry to four equivalent F1- atoms. All Pd–F bond lengths are 1.99 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 6-coordinate geometry to two equivalent Rb1+, three equivalent K1+, and one Pd2+ atom. In the second F1- site, F1- is bonded to two equivalent Rb1+ and four equivalent K1+ atoms to form corner-sharing FK4Rb2 octahedra. The corner-sharing octahedra tilt angles range from 0–33°.
