Materials Data on LiCO2 by Materials Project

LiCO2 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.03 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.90–2.11 Å. In the third Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.29 Å. There are three inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.26 Å) C–O bond length. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.25 Å. In the third C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.26 Å) C–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+ and one C3+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C3+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C3+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Li1+ and one C3+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ and one C3+ atom. In the sixth O2- site, O2- is bonded in a distorted T-shaped geometry to two Li1+ and one C3+ atom.
