Materials Data on KAgF3 by Materials Project

Abstract

KAgF3 is Orthorhombic Perovskite structured and 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 2.75–2.98 Å. Ag2+ is bonded to six F1- atoms to form corner-sharing AgF6 octahedra. The corner-sharing octahedra tilt angles range from 24–25°. There are a spread of Ag–F bond distances ranging from 2.11–2.45 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to two equivalent K1+ and two equivalent Ag2+ atoms. In the second F1- site, F1- is bonded in a 5-coordinate geometry to three equivalent K1+ and two equivalent Ag2+ atoms.
