Materials Data on Hg2SeO3 by Materials Project
Hg2SeO3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two Hg2SeO3 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Hg1+ sites. In the first Hg1+ site, Hg1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are one shorter (2.25 Å) and two longer (2.63 Å) Hg–O bond lengths. In the second Hg1+ site, Hg1+ is bonded in a 1-coordinate geometry to three O2- atoms. There are a spread of Hg–O bond distances ranging from 2.21–2.83 Å. Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.71–1.75 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Hg1+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Hg1+ and one Se4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Hg1+ and one Se4+ atom.
