All Li–O bond lengths are 1.89 Å. Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.44 Å) and four longer (2.46 Å) Gd–O bond lengths. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.48 Å) and two longer (1.52 Å) S–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Gd3+, and one S6+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Gd3+ and one S6+ atom.
