Materials Data on Li4(CuO2)3 by Materials Project

Abstract

Li4(CuO2)3 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 to four O2- atoms to form a mixture of distorted edge and corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.02 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of distorted edge and corner-sharing LiO4 trigonal pyramids. There are a spread of Li–O bond distances ranging from 1.95–2.08 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of distorted edge and corner-sharing LiO4 trigonal pyramids. There are a spread of Li–O bond distances ranging from 1.96–1.99 Å. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form a mixture of distorted edge and corner-sharing LiO4 trigonal pyramids. There are a spread of Li–O bond distances ranging from 1.94–2.06 Å. There are three inequivalent Cu+2.67+ sites. In the first Cu+2.67+ site, Cu+2.67+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.84–1.87 Å. In the second Cu+2.67+ site, Cu+2.67+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.85–1.89 Å. In the third Cu+2.67+ site, Cu+2.67+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.91–1.95 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+ and two Cu+2.67+ atoms to form a mixture of distorted edge and corner-sharing OLi3Cu2 trigonal bipyramids. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to two Li1+ and two Cu+2.67+ atoms. In the third O2- site, O2- is bonded in a rectangular see-saw-like geometry to two Li1+ and two Cu+2.67+ atoms. In the fourth O2- site, O2- is bonded to three Li1+ and two Cu+2.67+ atoms to form a mixture of edge and corner-sharing OLi3Cu2 trigonal bipyramids. In the fifth O2- site, O2- is bonded to three Li1+ and two Cu+2.67+ atoms to form a mixture of edge and corner-sharing OLi3Cu2 trigonal bipyramids. In the sixth O2- site, O2- is bonded to three Li1+ and two Cu+2.67+ atoms to form a mixture of edge and corner-sharing OLi3Cu2 trigonal bipyramids.
