Materials Data on KCuF3 by Materials Project
KCuF3 is (Cubic) Perovskite-like structured and crystallizes in the orthorhombic Pbca 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 CuF6 octahedra. There are a spread of K–F bond distances ranging from 2.88–2.93 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, 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 1°. There are a spread of Cu–F bond distances ranging from 1.94–2.12 Å. In the second Cu2+ site, 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 1°. There are a spread of Cu–F bond distances ranging from 1.97–2.20 Å. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to four equivalent K1+ and two Cu2+ atoms. In the second F1- site, F1- is bonded in a distorted linear geometry to four equivalent K1+ and two Cu2+ atoms. In the third F1- site, F1- is bonded in a 6-coordinate geometry to four equivalent K1+ and two Cu2+ atoms.
