description: Li7V6Ni5O24 is Spinel-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six VO4 tetrahedra, edges with three LiO6 octahedra, and edges with three NiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.09–2.14 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six VO4 tetrahedra, edges with three LiO6 octahedra, and edges with three NiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.10–2.14 Å. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six VO4 tetrahedra, edges with three LiO6 octahedra, and edges with three NiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.10–2.15 Å. In the fourth Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six VO4 tetrahedra, edges with two equivalent LiO6 octahedra, and edges with four NiO6 octahedra. There are two shorter (2.10 Å) and four longer (2.13 Å) Li–O bond lengths. There are three inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with five NiO6 octahedra and corners with seven LiO6 octahedra.

In the second Ni+2.20+ site, Ni+2.20+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six VO4 tetrahedra, edges with two equivalent NiO6 octahedra, and edges with four LiO6 octahedra. There are four shorter (2.06 Å) and two longer (2.07 Å) Ni–O bond lengths. In the third Ni+2.20+ site, Ni+2.20+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six VO4 tetrahedra, edges with two equivalent NiO6 octahedra, and edges with four LiO6 octahedra. All Ni–O bond lengths are 2.06 Å. In the fourth Ni+2.20+ site, Ni+2.20+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six VO4 tetrahedra, edges with two equivalent NiO6 octahedra, and edges with four LiO6 octahedra. There are a spread of Ni–O bond distances ranging from 2.05–2.07 Å. There are twelve inequivalent O2- sites.
