Li2Mn3TeO8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded to one O(1) 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 Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 58-62°. Mn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MnO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Te(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. Te(1) is bonded to six equivalent O(2) atoms to form TeO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra and edges with six equivalent Mn(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(1) and three equivalent Mn(1) atoms to form corner-sharing OLiMn3 tetrahedra. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Mn(1), and one Te(1) atom.
