Abstract

LiCu2(CO3)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Li1+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.00 Å. There are two inequivalent Cu+1.50+ sites. In the first Cu+1.50+ site, Cu+1.50+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.90–2.41 Å. In the second Cu+1.50+ site, Cu+1.50+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.90–2.27 Å. There are two 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 1.28–1.31 Å. In the second 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 1.28–1.31 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Cu+1.50+, and one C4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu+1.50+, and one C4+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu+1.50+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Cu+1.50+, and one C4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu+1.50+ and one C4+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu+1.50+, and one C4+ atom.
