Materials Data on Cs2AgF4 by Materials Project
Cs2AgF4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Cs1+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Cs–F bond distances ranging from 3.04–3.23 Å. Ag2+ is bonded to six F1- atoms to form corner-sharing AgF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.21 Å) and four longer (2.29 Å) Ag–F bond lengths. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded to five equivalent Cs1+ and one Ag2+ atom to form distorted FCs5Ag octahedra that share corners with seventeen FCs5Ag octahedra, edges with eight equivalent FCs5Ag octahedra, and faces with four equivalent FCs4Ag2 octahedra. The corner-sharing octahedra tilt angles range from 0–57°. In the second F1- site, F1- is bonded to four equivalent Cs1+ and two equivalent Ag2+ atoms to form distorted FCs4Ag2 octahedra that share corners with fourteen FCs5Ag octahedra, edges with two equivalent FCs4Ag2 octahedra, and faces with eight FCs5Ag octahedra. The corner-sharing octahedra tilt angles range from 0–57°.
