Materials Data on Li2CrNiO4 by Materials Project
Li2CrNiO4 is alpha Po-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent NiO6 octahedra, edges with two equivalent NiO6 octahedra, edges with four equivalent CrO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–7°. There are a spread of Li–O bond distances ranging from 2.07–2.15 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent CrO6 octahedra, edges with two equivalent CrO6 octahedra, edges with four equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–5°. There are a spread of Li–O bond distances ranging from 2.12–2.18 Å. Cr4+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent CrO6 octahedra, edges with four equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 4–5°. There is two shorter (1.97 Å) and four longer (1.99 Å) Cr–O bond length. Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent NiO6 octahedra, edges with four equivalent CrO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–7°. There are a spread of Ni–O bond distances ranging from 2.00–2.08 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, one Cr4+, and two equivalent Ni2+ atoms to form a mixture of edge and corner-sharing OLi3CrNi2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to three Li1+, two equivalent Cr4+, and one Ni2+ atom to form OLi3Cr2Ni octahedra that share corners with six equivalent OLi3Cr2Ni octahedra and edges with twelve OLi3CrNi2 octahedra. The corner-sharing octahedral tilt angles are 0°.
