In the first Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to ten Te+1.08- atoms. There are a spread of Rb–Te bond distances ranging from 3.77–4.44 Å. In the second Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven Te+1.08- atoms. There are a spread of Rb–Te bond distances ranging from 3.71–3.97 Å. In the third Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven Te+1.08- atoms. There are a spread of Rb–Te bond distances ranging from 3.86–4.12 Å. There are three inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded to four Te+1.08- atoms to form distorted corner-sharing HgTe4 tetrahedra.
