Abstract

In the first Li1+ site, Li1+ is bonded in a distorted rectangular see-saw-like geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.99–2.66 Å. In the second Li1+ site, Li1+ is bonded in a distorted rectangular see-saw-like geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.69 Å.
