Abstract

Li4MnCo2O7 crystallizes in the triclinic P1 space group. The structure is one-dimensional and consists of one Li4MnCo2O7 ribbon oriented in the (4, 5, 3) direction. there are eight inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.22 Å) and one longer (1.30 Å) Li–O bond length. In the second Li1+ site, Li1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.14 Å) and one longer (1.18 Å) Li–O bond length. In the third Li1+ site, Li1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.28 Å) and one longer (1.32 Å) Li–O bond length. In the fourth Li1+ site, Li1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.19 Å) and one longer (1.20 Å) Li–O bond length. In the fifth Li1+ site, Li1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.24 Å) Li–O bond length. In the sixth Li1+ site, Li1+ is bonded in a bent 150 degrees geometry to two O2- atoms. There is one shorter (1.17 Å) and one longer (1.41 Å) Li–O bond length. In the seventh Li1+ site, Li1+ is bonded in a bent 150 degrees geometry to two O2- atoms. There is one shorter (1.15 Å) and one longer (1.40 Å) Li–O bond length. In the eighth Li1+ site, Li1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.31 Å) Li–O bond length. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.22 Å) and one longer (1.25 Å) Mn–O bond length. In the second Mn2+ site, Mn2+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.10 Å) and one longer (1.30 Å) Mn–O bond length. There are four inequivalent Co4+ sites. In the first Co4+ site, Co4+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.07 Å) and one longer (1.14 Å) Co–O bond length. In the second Co4+ site, Co4+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.21 Å) and one longer (1.28 Å) Co–O bond length. In the third Co4+ site, Co4+ is bonded in a bent 150 degrees geometry to two O2- atoms. There is one shorter (1.15 Å) and one longer (1.33 Å) Co–O bond length. In the fourth Co4+ site, Co4+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.26 Å) Co–O bond length. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Li1+ and one Mn2+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one Co4+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Li1+ and one Co4+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Li1+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to one Li1+ and one Co4+ atom. In the sixth O2- site, O2- is bonded in a linear geometry to one Li1+ and one Mn2+ atom. In the seventh O2- site, O2- is bonded in a distorted linear geometry to one Li1+ and one Co4+ atom.
