Materials Data on RbAgF3 by Materials Project

Abstract

RbAgF3 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Rb1+ is bonded in a 2-coordinate geometry to two equivalent F1- atoms. Both Rb–F bond lengths are 2.63 Å. Ag2+ is bonded to six F1- atoms to form corner-sharing AgF6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. There are four shorter (2.15 Å) and two longer (2.18 Å) Ag–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to two equivalent Ag2+ atoms. In the second F1- site, F1- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Rb1+ and two equivalent Ag2+ atoms.
