description: Li2Co(CO3)2 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 3-coordinate geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.93–2.03 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with two CoO6 octahedra, an edgeedge with one CoO6 octahedra, and an edgeedge with one LiO4 trigonal pyramid. The corner-sharing octahedra tilt angles range from 37–84°. There are a spread of Li–O bond distances ranging from 1.97–2.15 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with two CoO6 octahedra and an edgeedge with one CoO6 octahedra. The corner-sharing octahedra tilt angles range from 41–79°. There are a spread of Li–O bond distances ranging from 1.98–2.09 Å. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share corners with two CoO6 octahedra, an edgeedge with one CoO6 octahedra, and an edgeedge with one LiO4 trigonal pyramid. The corner-sharing octahedra tilt angles range from 37–82°. There are a spread of Li–O bond distances ranging from 1.96–2.15 Å. There are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with three LiO4 trigonal pyramids and edges with two LiO4 trigonal pyramids. There are a spread of Co–O bond distances ranging from 2.07–2.19 Å. In the second Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with three LiO4 trigonal pyramids and an edgeedge with one LiO4 trigonal pyramid. There are a spread of Co–O bond distances ranging from 2.06–2.27 Å. There are four inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.29 Å) and one longer (1.31 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length. In the third C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length. In the fourth 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 1.29–1.31 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Co2+, and one C4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Co2+, and one C4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Co2+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Co2+, and one C4+ atom. In the fifth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Co2+, and one C4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Co2+, and one C4+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Co2+, and one C4+ atom. In the eighth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Co2+, and one C4+ atom.
