The Materials Project

KCuF3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. K1+ is bonded in a square co-planar geometry to four equivalent F1- atoms. All K–F bond lengths are 2.59 Å. Cu2+ is bonded in a square co-planar geometry to four F1- atoms. There is two shorter (1.87 Å) and two longer (1.92 Å) Cu–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to two equivalent Cu2+ atoms. In the second F1- site, F1- is bonded in a 3-coordinate geometry to two equivalent K1+ and one Cu2+ atom.
