description: Co2(CO3)3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Co3+ sites. In the first Co3+ site, Co3+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedra tilt angles range from 67–70°. There are a spread of Co–O bond distances ranging from 1.89–2.18 Å. In the second Co3+ site, Co3+ is bonded to six O2- atoms to form distorted corner-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 70°. There are a spread of Co–O bond distances ranging from 1.90–2.26 Å. In the third Co3+ site, Co3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Co–O bond distances ranging from 2.00–2.57 Å. In the fourth Co3+ site, Co3+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedra tilt angles range from 67–70°. There are a spread of Co–O bond distances ranging from 1.90–2.23 Å. There are six inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.28 Å) and two longer (1.30 Å) C–O bond length. In the second 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 third 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 1.27–1.31 Å. 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 1.27–1.32 Å. In the fifth 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 1.27–1.31 Å. In the sixth C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.29 Å) and one longer (1.30 Å) C–O bond length. There are eighteen inequivalent O2- sites.
