Materials Data on Li2(NiO2)3 by Materials Project
Li2(NiO2)3 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 NiO6 octahedra, edges with three equivalent LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 10–11°. There are a spread of Li–O bond distances ranging from 2.08–2.19 Å. There are two inequivalent Ni+3.33+ sites. In the first Ni+3.33+ site, Ni+3.33+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four equivalent LiO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 10–11°. There are a spread of Ni–O bond distances ranging from 1.88–2.00 Å. In the second Ni+3.33+ site, Ni+3.33+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with four equivalent LiO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with six equivalent NiO6 octahedra. The corner-sharing octahedral tilt angles are 11°. There is two shorter (1.89 Å) and four longer (2.01 Å) Ni–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+ and three Ni+3.33+ atoms to form a mixture of edge and corner-sharing OLi2Ni3 square pyramids. In the second O2- site, O2- is bonded to two equivalent Li1+ and three Ni+3.33+ atoms to form a mixture of edge and corner-sharing OLi2Ni3 square pyramids.
