Title: Materials Data on KCuF3 by Materials Project

Abstract

KCuF3 is (Cubic) Perovskite structured and crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. K1+ is bonded to twelve F1- atoms to form KF12 cuboctahedra that share corners with twelve equivalent KF12 cuboctahedra, faces with six equivalent KF12 cuboctahedra, and faces with eight equivalent CuF6 octahedra. All K–F bond lengths are 2.88 Å. Cu2+ is bonded to six F1- atoms to form CuF6 octahedra that share corners with six equivalent CuF6 octahedra and faces with eight equivalent KF12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are a spread of Cu–F bond distances ranging from 1.98–2.10 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to four equivalent K1+ and two equivalent Cu2+ atoms. In the second F1- site, F1- is bonded in a distorted linear geometry to four equivalent K1+ and two equivalent Cu2+ atoms.
