Materials Data on Li2TiNiO4 by Materials Project
Li2NiTiO4 is alpha Po-derived structured and crystallizes in the orthorhombic Imma 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 TiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedral tilt angles are 7°. There are two shorter (2.06 Å) and four longer (2.14 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent TiO6 octahedra, edges with two equivalent TiO6 octahedra, edges with four equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 2–5°. There are two shorter (2.19 Å) and four longer (2.20 Å) Li–O bond lengths. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with two equivalent TiO6 octahedra, edges with four equivalent NiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedra tilt angles range from 2–5°. There is two shorter (1.96 Å) and four longer (2.01 Å) Ti–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 TiO6 octahedra, and edges with six LiO6 octahedra. The corner-sharing octahedral tilt angles are 7°. There are four shorter (2.08 Å) and two longer (2.10 Å) Ni–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three Li1+, one Ti4+, and two equivalent Ni2+ atoms to form a mixture of edge and corner-sharing OLi3TiNi2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to three Li1+, two equivalent Ti4+, and one Ni2+ atom to form OLi3Ti2Ni octahedra that share corners with six equivalent OLi3Ti2Ni octahedra and edges with twelve OLi3TiNi2 octahedra. The corner-sharing octahedral tilt angles are 0°.
