The structure described by Li2Ni3TeO8 is Spinel-derived structured and crystallizes in the monoclinic C2/m space group. Li(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with three equivalent Ni(2)O6 octahedra, corners with three equivalent Te(1)O6 octahedra, and corners with six equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 56-66°. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NiO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Ni(1)O6 octahedra, edges with two equivalent Ni(2)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. In the second Ni site, Ni(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form NiO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Te(1)O6 octahedra, and edges with four equivalent Ni(1)O6 octahedra. Te(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form TeO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Ni(2)O6 octahedra, and edges with four equivalent Ni(1)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Ni(2), and two equivalent Ni(1) atoms to form distorted OLiNi3 tetrahedra that share corners with three equivalent O(1)LiNi3 tetrahedra, corners with six equivalent O(2)LiNi2Te trigonal pyramids, and edges with two equivalent O(2)LiNi2Te trigonal pyramids. In the second O site, O(2) is bonded to one Li(1), one Ni(1), one Ni(2), and one Te(1) atom to form distorted OLiNi2Te trigonal pyramids that share corners with three equivalent O(1)LiNi3 tetrahedra, corners with six equivalent O(2)LiNi2Te trigonal pyramids,  an edgeedge with one O(1)LiNi3 tetrahedra, and  an edgeedge with one O(2)LiNi2Te trigonal pyramid. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Ni(1), and one Te(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
