Materials Data on NaCuF3 by Materials Project

NaCuF3 is Orthorhombic Perovskite structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Na–F bond distances ranging from 2.29–2.98 Å. In the second Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven F1- atoms. There are a spread of Na–F bond distances ranging from 2.31–2.70 Å. There are four inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 31–37°. There are a spread of Cu–F bond distances ranging from 1.91–2.31 Å. In the second Cu2+ site, Cu2+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 31–35°. There are a spread of Cu–F bond distances ranging from 1.91–2.29 Å. In the third Cu2+ site, Cu2+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 34–37°. There are a spread of Cu–F bond distances ranging from 1.91–2.32 Å. In the fourth Cu2+ site, Cu2+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedral tilt angles are 34°. There are a spread of Cu–F bond distances ranging from 1.91–2.28 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a 4-coordinate geometry to two Na1+ and two Cu2+ atoms. In the second F1- site, F1- is bonded to two Na1+ and two Cu2+ atoms to form distorted corner-sharing FNa2Cu2 tetrahedra. In the third F1- site, F1- is bonded in a 5-coordinate geometry to three Na1+ and two Cu2+ atoms. In the fourth F1- site, F1- is bonded in a 4-coordinate geometry to three Na1+ and two Cu2+ atoms. In the fifth F1- site, F1- is bonded in a 5-coordinate geometry to three Na1+ and two Cu2+ atoms. In the sixth F1- site, F1- is bonded in a 4-coordinate geometry to two Na1+ and two Cu2+ atoms.
