In the first Cs1+ site, Cs1+ is bonded in a 1-coordinate geometry to twelve O2- atoms. There are a spread of Cs–O bond distances ranging from 3.19–3.66 Å. In the second Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cs–O bond distances ranging from 3.05–3.26 Å. In the third Cs1+ site, Cs1+ is bonded in a 7-coordinate geometry to six O2- atoms. There are a spread of Cs–O bond distances ranging from 3.03–3.26 Å. In the fourth Cs1+ site, Cs1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Cs–O bond distances ranging from 3.16–3.66 Å. There are four inequivalent Mg2+ sites.
