Materials Data on Li2Cu2F7 by Materials Project
Abstract
Li2Cu2F7 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four F1- atoms. There are a spread of Li–F bond distances ranging from 2.00–2.09 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 1.97–2.56 Å. In the third 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 1.97–2.56 Å. In the fourth Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four F1- atoms. There are a spread of Li–F bond distances ranging from 2.00–2.08 Å. There are four inequivalent Cu+2.50+ sites. In the first Cu+2.50+ site, Cu+2.50+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 14–34°. There are a spread of Cu–F bond distances ranging from 1.91–1.99 Å. In the second Cu+2.50+ site, Cu+2.50+ is bonded to six F1- atoms to form corner-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 16–29°. There aremore »
