The crystal structure described by Li2Ni3TeO8 is Spinel-derived structured and crystallizes in the hexagonal P6_3mc space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(3) and three equivalent O(2) atoms to form LiO4 tetrahedra that share corners with three equivalent Te(1)O6 octahedra and corners with nine equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-60°. In the second Li site, Li(2) is bonded to one O(4) and three equivalent O(1) atoms to form distorted LiO4 tetrahedra that share corners with three equivalent Ni(1)O6 octahedra, corners with three equivalent Te(1)O6 octahedra, and edges with three equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 61-66°. Ni(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form NiO6 octahedra that share corners with two equivalent Te(1)O6 octahedra,  a cornercorner with one Li(2)O4 tetrahedra, corners with three equivalent Li(1)O4 tetrahedra,  an edgeedge with one Te(1)O6 octahedra, edges with four equivalent Ni(1)O6 octahedra, and  an edgeedge with one Li(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. Te(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form TeO6 octahedra that share corners with six equivalent Ni(1)O6 octahedra, corners with three equivalent Li(1)O4 tetrahedra, corners with three equivalent Li(2)O4 tetrahedra, and edges with three equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Li(2), two equivalent Ni(1), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), two equivalent Ni(1), and one Te(1) atom. In the third O site, O(3) is bonded to one Li(1) and three equivalent Ni(1) atoms to form distorted corner-sharing OLiNi3 tetrahedra. In the fourth O site, O(4) is bonded to one Li(2) and three equivalent Ni(1) atoms to form corner-sharing OLiNi3 tetrahedra. is represented by the CIF card [CIF]
