Title: Materials Data on Hg8Br3O4 by Materials Project

Abstract

HgBrHg7(O2Br)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two HgBr ribbons oriented in the (0, 1, 0) direction and two Hg7(O2Br)2 sheets oriented in the (0, 0, 1) direction. In each HgBr ribbon, Hg+1.38+ is bonded in a 2-coordinate geometry to one Hg+1.38+ and two equivalent Br1- atoms. The Hg–Hg bond length is 2.64 Å. There are one shorter (2.58 Å) and one longer (3.01 Å) Hg–Br bond lengths. Br1- is bonded in an L-shaped geometry to two equivalent Hg+1.38+ atoms. In each Hg7(O2Br)2 sheet, there are seven inequivalent Hg+1.38+ sites. In the first Hg+1.38+ site, Hg+1.38+ is bonded in a distorted see-saw-like geometry to two O2- and two Br1- atoms. There are one shorter (2.18 Å) and one longer (2.39 Å) Hg–O bond lengths. There are one shorter (2.66 Å) and one longer (2.90 Å) Hg–Br bond lengths. In the second Hg+1.38+ site, Hg+1.38+ is bonded in a 4-coordinate geometry to three O2- and one Br1- atom. There are a spread of Hg–O bond distances ranging from 2.18–2.52 Å. The Hg–Br bond length is 2.88 Å. In the third Hg+1.38+ site, Hg+1.38+ is bonded in an L-shaped geometry to two O2- atoms.more » There are one shorter (2.39 Å) and one longer (2.41 Å) Hg–O bond lengths. In the fourth Hg+1.38+ site, Hg+1.38+ is bonded in a 1-coordinate geometry to three O2- and one Br1- atom. There are a spread of Hg–O bond distances ranging from 2.54–2.92 Å. The Hg–Br bond length is 3.48 Å. In the fifth Hg+1.38+ site, Hg+1.38+ is bonded in a distorted linear geometry to two O2- and one Br1- atom. There are one shorter (2.03 Å) and one longer (2.08 Å) Hg–O bond lengths. The Hg–Br bond length is 3.13 Å. In the sixth Hg+1.38+ site, Hg+1.38+ is bonded in a distorted single-bond geometry to one O2- and three Br1- atoms. The Hg–O bond length is 2.20 Å. There are a spread of Hg–Br bond distances ranging from 3.25–3.33 Å. In the seventh Hg+1.38+ site, Hg+1.38+ is bonded in a trigonal planar geometry to three O2- and one Br1- atom. There are a spread of Hg–O bond distances ranging from 2.22–2.29 Å. The Hg–Br bond length is 3.30 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to four Hg+1.38+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to four Hg+1.38+ atoms. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to four Hg+1.38+ atoms. In the fourth O2- site, O2- is bonded to four Hg+1.38+ atoms to form distorted corner-sharing OHg4 tetrahedra. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 1-coordinate geometry to four Hg+1.38+ atoms. In the second Br1- site, Br1- is bonded in a 2-coordinate geometry to five Hg+1.38+ atoms.« less
