There is three shorter (1.46 Å) and one longer (1.63 Å) S–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one S6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Li1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Li1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to two S6+ atoms.
