Materials Data on Li2Mn3O6 by Materials Project
Li2Mn3O6 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six MnO6 octahedra, edges with three equivalent LiO6 octahedra, and edges with six MnO6 octahedra. The corner-sharing octahedra tilt angles range from 10–15°. There are a spread of Li–O bond distances ranging from 2.15–2.20 Å. There are two inequivalent Mn+3.33+ sites. In the first Mn+3.33+ site, Mn+3.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent LiO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with six MnO6 octahedra. The corner-sharing octahedra tilt angles range from 10–15°. There are a spread of Mn–O bond distances ranging from 1.92–2.31 Å. In the second Mn+3.33+ site, Mn+3.33+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent LiO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with six equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 10°. There is four shorter (1.95 Å) and two longer (1.97 Å) Mn–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+ and three Mn+3.33+ atoms to form a mixture of edge and corner-sharing OLi2Mn3 square pyramids. In the second O2- site, O2- is bonded to two equivalent Li1+ and three Mn+3.33+ atoms to form a mixture of edge and corner-sharing OLi2Mn3 square pyramids.
