Materials Data on SiHg3(SF3)2 by Materials Project

Abstract

Hg3Si(SF3)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Hg2+ is bonded in a distorted hexagonal planar geometry to two equivalent S2- and four equivalent F1- atoms. Both Hg–S bond lengths are 2.38 Å. All Hg–F bond lengths are 2.97 Å. Si4+ is bonded in an octahedral geometry to six equivalent F1- atoms. All Si–F bond lengths are 1.72 Å. S2- is bonded in a distorted hexagonal planar geometry to three equivalent Hg2+ and three equivalent F1- atoms. All S–F bond lengths are 2.89 Å. F1- is bonded in a single-bond geometry to two equivalent Hg2+, one Si4+, and one S2- atom.
