The material described by Li6Mn5SbO12 is Ilmenite-derived structured and crystallizes in the monoclinic C2/m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(3), and two equivalent O(2) atoms.
