Materials Data on Hg2TeO3 by Materials Project
Hg2TeO3 crystallizes in the orthorhombic Pma2 space group. The structure is two-dimensional and consists of one Hg2TeO3 sheet oriented in the (0, 1, 0) direction. Hg1+ is bonded in a 1-coordinate geometry to two equivalent O2- atoms. There are one shorter (2.19 Å) and one longer (2.78 Å) Hg–O bond lengths. Te4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Te–O bond distances ranging from 1.87–2.91 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Hg1+ and two equivalent Te4+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Te4+ atom.
