In the first Hg2+ site, Hg2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Hg–O bond distances ranging from 2.10–2.79 Å. In the second Hg2+ site, Hg2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Hg–O bond distances ranging from 2.24–3.00 Å. In the third Hg2+ site, Hg2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Hg–O bond distances ranging from 2.30–2.69 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–1.94 Å. In the second Te4+ site, Te4+ is bonded in a 6-coordinate geometry to three O2- atoms. There is one shorter (1.91 Å) and two longer (1.92 Å) Te–O bond length. Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.67–1.70 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Hg2+ and one Te4+ atom.
