In the first Gd3+ site, Gd3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Gd–O bond distances ranging from 2.24–2.61 Å. In the second Gd3+ site, Gd3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Gd–O bond distances ranging from 2.11–2.68 Å. In the third Gd3+ site, Gd3+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Gd–O bond distances ranging from 2.22–2.79 Å. In the fourth Gd3+ site, Gd3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Gd–O bond distances ranging from 2.19–2.77 Å.
