Li4Ni3AlO8 is alpha Po-derived structured and crystallizes in the trigonal R-3m 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 three equivalent NiO6 octahedra, corners with three equivalent AlO6 octahedra, edges with three equivalent NiO6 octahedra, edges with three equivalent AlO6 octahedra, and edges with six equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 6–8°. There are three shorter (2.13 Å) and three longer (2.16 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 NiO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedral tilt angles are 5°. There are three shorter (2.11 Å) and three longer (2.12 Å) Li–O bond lengths. There are two inequivalent Ni3+ sites. In the first Ni3+ site, Ni3+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six LiO6 octahedra, edges with six LiO6 octahedra, and edges with six equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 5–6°. There is three shorter (1.98 Å) and three longer (1.99 Å) Ni–O bond length. In the second Ni3+ site, Ni3+ is bonded to six equivalent O2- atoms to form NiO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent NiO6 octahedra. The corner-sharing octahedral tilt angles are 5°. All Ni–O bond lengths are 1.99 Å. Al3+ is bonded to six equivalent O2- atoms to form AlO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent AlO6 octahedra. The corner-sharing octahedral tilt angles are 8°. All Al–O bond lengths are 1.94 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Li1+ and three equivalent Ni3+ atoms to form OLi3Ni3 octahedra that share corners with six OLi3Al3 octahedra and edges with twelve OLi3Ni3 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. In the second O2- site, O2- is bonded to three equivalent Li1+ and three equivalent Ni3+ atoms to form a mixture of edge and corner-sharing OLi3Ni3 octahedra. The corner-sharing octahedral tilt angles are 0°. In the third O2- site, O2- is bonded to three equivalent Li1+ and three equivalent Al3+ atoms to form a mixture of edge and corner-sharing OLi3Al3 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. In the fourth O2- site, O2- is bonded to three equivalent Li1+ and three equivalent Ni3+ atoms to form a mixture of edge and corner-sharing OLi3Ni3 octahedra. The corner-sharing octahedral tilt angles are 0°.
