Materials Data on Hg4SbO6 by Materials Project

Hg4SbO6 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one Hg4SbO6 sheet oriented in the (0, 0, 1) direction. there are four inequivalent Hg+1.75+ sites. In the first Hg+1.75+ site, Hg+1.75+ is bonded in a 2-coordinate geometry to two O2- atoms. There are one shorter (2.27 Å) and one longer (2.28 Å) Hg–O bond lengths. In the second Hg+1.75+ site, Hg+1.75+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Hg–O bond distances ranging from 2.11–2.30 Å. In the third Hg+1.75+ site, Hg+1.75+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Hg–O bond distances ranging from 2.11–2.30 Å. In the fourth Hg+1.75+ site, Hg+1.75+ is bonded in a 2-coordinate geometry to two O2- atoms. There are one shorter (2.27 Å) and one longer (2.28 Å) Hg–O bond lengths. Sb5+ is bonded in an octahedral geometry to six O2- atoms. There are two shorter (1.96 Å) and four longer (2.11 Å) Sb–O bond lengths. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two Hg+1.75+ and one Sb5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Hg+1.75+ and one Sb5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Hg+1.75+ and one Sb5+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two Hg+1.75+ and one Sb5+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two Hg+1.75+ and one Sb5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Hg+1.75+ and one Sb5+ atom.
