Materials Data on LiCu2(C2O5)2 by Materials Project
LiCu2(C2O5)2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.92–2.65 Å. There are two inequivalent Cu+1.50+ sites. In the first Cu+1.50+ site, Cu+1.50+ is bonded in a distorted octahedral geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.99–2.45 Å. In the second Cu+1.50+ site, Cu+1.50+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.84 Å) and one longer (1.87 Å) Cu–O bond length. There are four inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.24–1.43 Å.
