In the second Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.00–2.43 Å. In the third Li1+ site, Li1+ is bonded in a 3-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.96–2.51 Å. Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with six TeO6 octahedra. The corner-sharing octahedra tilt angles range from 32–42°. There are a spread of Zr–O bond distances ranging from 2.06–2.17 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six TeO6 octahedra. The corner-sharing octahedra tilt angles range from 31–40°. There are a spread of Nb–O bond distances ranging from 1.96–2.09 Å. There are two inequivalent Te6+ sites. In the first Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent NbO6 octahedra and corners with four equivalent ZrO6 octahedra. The corner-sharing octahedra tilt angles range from 32–42°. There are a spread of Te–O bond distances ranging from 1.90–2.03 Å. In the second Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent ZrO6 octahedra and corners with four equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 31–40°. There are a spread of Te–O bond distances ranging from 1.88–2.00 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Nb5+, and one Te6+ atom.
