Materials Data on Rb2Hg3Te4 by Materials Project
Rb2Hg3Te4 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Rb1+ is bonded in a 7-coordinate geometry to seven Te2- atoms. There are a spread of Rb–Te bond distances ranging from 3.76–4.18 Å. There are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a tetrahedral geometry to four Te2- atoms. All Hg–Te bond lengths are 2.92 Å. In the second Hg2+ site, Hg2+ is bonded in a 3-coordinate geometry to three Te2- atoms. There are a spread of Hg–Te bond distances ranging from 2.76–2.98 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 6-coordinate geometry to four equivalent Rb1+ and two Hg2+ atoms. In the second Te2- site, Te2- is bonded in a 6-coordinate geometry to three equivalent Rb1+ and three Hg2+ atoms.
