Materials Data on Hg5(SbI3)2 by Materials Project
Hg5(SbI3)2 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are five inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a distorted rectangular see-saw-like geometry to one Sb2- and three I1- atoms. The Hg–Sb bond length is 2.75 Å. There are a spread of Hg–I bond distances ranging from 2.78–3.28 Å. In the second Hg2+ site, Hg2+ is bonded in a 1-coordinate geometry to one Sb2- and two I1- atoms. The Hg–Sb bond length is 2.73 Å. There are one shorter (2.73 Å) and one longer (3.41 Å) Hg–I bond lengths. In the third Hg2+ site, Hg2+ is bonded in a distorted rectangular see-saw-like geometry to one Sb2- and three I1- atoms. The Hg–Sb bond length is 2.74 Å. There are a spread of Hg–I bond distances ranging from 2.84–3.55 Å. In the fourth Hg2+ site, Hg2+ is bonded in a rectangular see-saw-like geometry to one Sb2- and three I1- atoms. The Hg–Sb bond length is 2.75 Å. There are a spread of Hg–I bond distances ranging from 2.98–3.14 Å. In the fifth Hg2+ site, Hg2+ is bonded in a 5-coordinate geometry to one Sb2- and four I1- atoms. The Hg–Sb bond length is 2.78 Å. There are a spread of Hg–I bond distances ranging from 2.83–3.87 Å. There are two inequivalent Sb2- sites. In the first Sb2- site, Sb2- is bonded in a 3-coordinate geometry to two Hg2+ and one Sb2- atom. The Sb–Sb bond length is 2.89 Å. In the second Sb2- site, Sb2- is bonded in a tetrahedral geometry to three Hg2+ and one Sb2- atom. There are six inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted L-shaped geometry to two Hg2+ atoms. In the second I1- site, I1- is bonded in a water-like geometry to two Hg2+ atoms. In the third I1- site, I1- is bonded in a distorted L-shaped geometry to two Hg2+ atoms. In the fourth I1- site, I1- is bonded in a distorted trigonal non-coplanar geometry to three Hg2+ atoms. In the fifth I1- site, I1- is bonded in a 2-coordinate geometry to three Hg2+ atoms. In the sixth I1- site, I1- is bonded in a 3-coordinate geometry to three Hg2+ atoms.
