Materials Data on Li2CuF5 by Materials Project
Li2CuF5 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.94–2.51 Å. In the second Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.95–2.52 Å. There are two inequivalent Cu3+ sites. In the first Cu3+ site, Cu3+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedral tilt angles are 18°. There are a spread of Cu–F bond distances ranging from 1.88–1.97 Å. In the second Cu3+ site, Cu3+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedral tilt angles are 17°. There are a spread of Cu–F bond distances ranging from 1.88–1.96 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to two Li1+ and one Cu3+ atom. In the second F1- site, F1- is bonded in a distorted see-saw-like geometry to two equivalent Li1+ and two equivalent Cu3+ atoms. In the third F1- site, F1- is bonded to three Li1+ and one Cu3+ atom to form a mixture of distorted edge and corner-sharing FLi3Cu trigonal pyramids. In the fourth F1- site, F1- is bonded to three Li1+ and one Cu3+ atom to form a mixture of distorted edge and corner-sharing FLi3Cu trigonal pyramids. In the fifth F1- site, F1- is bonded in a distorted see-saw-like geometry to two equivalent Li1+ and two equivalent Cu3+ atoms. In the sixth F1- site, F1- is bonded in a distorted trigonal non-coplanar geometry to two Li1+ and one Cu3+ atom.
