description: Li4Ti3Ni3(TeO8)2 is Hausmannite-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent TeO6 octahedra, corners with four TiO6 octahedra, and corners with five NiO6 octahedra. The corner-sharing octahedra tilt angles range from 53–63°. There are a spread of Li–O bond distances ranging from 1.95–2.02 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share a cornercorner with one TiO6 octahedra, corners with two equivalent NiO6 octahedra, corners with three equivalent TeO6 octahedra, an edgeedge with one NiO6 octahedra, and edges with two equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 61–66°. There are a spread of Li–O bond distances ranging from 1.83–2.05 Å. In the third Li1+ site, Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are two shorter (1.98 Å) and two longer (2.12 Å) Li–O bond lengths. In the fourth Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four NiO6 octahedra and corners with five TiO6 octahedra.

There are a spread of Te–O bond distances ranging from 1.93–2.56 Å. In the second Te4+ site, Te4+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent NiO6 octahedra, corners with four equivalent TiO6 octahedra, corners with six LiO4 tetrahedra, an edgeedge with one TiO6 octahedra, and edges with two equivalent NiO6 octahedra. The corner-sharing octahedra tilt angles range from 49–52°. There are a spread of Te–O bond distances ranging from 1.95–2.02 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+, one Ti4+, one Ni+2.67+, and one Te4+ atom.
