Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six TeO6 octahedra. The corner-sharing octahedra tilt angles range from 34–40°. There are a spread of Fe–O bond distances ranging from 1.98–2.16 Å. Bi5+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with six TeO6 octahedra. The corner-sharing octahedra tilt angles range from 43–47°. There are a spread of Bi–O bond distances ranging from 2.10–2.17 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 BiO6 octahedra and corners with four equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 34–45°. There are a spread of Te–O bond distances ranging from 1.92–1.99 Å. In the second Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent FeO6 octahedra and corners with four equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 39–47°. There are a spread of Te–O bond distances ranging from 1.91–2.00 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Bi5+, and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+, one Fe3+, and one Te6+ atom. In the third O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+, one Fe3+, and one Te6+ atom. In the fourth O2- site, O2- is bonded to two Li1+, one Bi5+, and one Te6+ atom to form a mixture of distorted corner and edge-sharing OLi2BiTe tetrahedra. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Fe3+, and one Te6+ atom. In the sixth O2- site, O2- is bonded to two Li1+, one Fe3+, and one Te6+ atom to form distorted OLi2FeTe tetrahedra that share a cornercorner with one OLi2BiTe tetrahedra, corners with two equivalent OLi2FeTe trigonal pyramids, and an edgeedge with one OLi2BiTe tetrahedra. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Bi5+, and one Te6+ atom. In the eighth O2- site, O2- is bonded to two Li1+, one Fe3+, and one Te6+ atom to form distorted corner-sharing OLi2FeTe trigonal pyramids. In the ninth O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+, one Fe3+, and one Te6+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Bi5+, and one Te6+ atom. In the eleventh O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Bi5+, and one Te6+ atom. In the twelfth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Bi5+, and one Te6+ atom.
