Materials Data on Hg2SbF6 by Materials Project

Abstract

Hg2SbF6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Hg+1.50+ sites. In the first Hg+1.50+ site, Hg+1.50+ is bonded in a distorted rectangular see-saw-like geometry to four F1- atoms. There are two shorter (2.89 Å) and two longer (2.95 Å) Hg–F bond lengths. In the second Hg+1.50+ site, Hg+1.50+ is bonded in a 4-coordinate geometry to four F1- atoms. There are two shorter (2.86 Å) and two longer (2.94 Å) Hg–F bond lengths. Sb3+ is bonded in an octahedral geometry to six F1- atoms. All Sb–F bond lengths are 1.92 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Hg+1.50+ and one Sb3+ atom. In the second F1- site, F1- is bonded in a distorted single-bond geometry to two Hg+1.50+ and one Sb3+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the fourth F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Hg+1.50+ and one Sb3+ atom. In the fifth F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Hg+1.50+ and one Sb3+ atom. Both F–Hg bond lengths are 2.94 Å. The F–Sb bond length is 1.92 Å. In the sixth F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Hg+1.50+ and one Sb3+ atom. Both F–Hg bond lengths are 2.89 Å. The F–Sb bond length is 1.92 Å.
