Title: Materials Data on SnHg2(SBr)2 by Materials Project

Abstract

Hg2Sn(SBr)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a 2-coordinate geometry to two S2- and three Br1- atoms. Both Hg–S bond lengths are 2.40 Å. There are two shorter (3.38 Å) and one longer (3.43 Å) Hg–Br bond lengths. In the second Hg2+ site, Hg2+ is bonded in a 2-coordinate geometry to three S2- and two equivalent Br1- atoms. There are a spread of Hg–S bond distances ranging from 2.40–3.08 Å. There are one shorter (3.46 Å) and one longer (3.56 Å) Hg–Br bond lengths. Sn2+ is bonded to two S2- and three Br1- atoms to form distorted edge-sharing SnS2Br3 square pyramids. There are one shorter (3.01 Å) and one longer (3.08 Å) Sn–S bond lengths. There are a spread of Sn–Br bond distances ranging from 2.84–2.96 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 3-coordinate geometry to two Hg2+ and one Sn2+ atom. In the second S2- site, S2- is bonded in a 4-coordinate geometry to three Hg2+ and one Sn2+ atom. There are two inequivalent Br1- sites. In the firstmore » Br1- site, Br1- is bonded in a 1-coordinate geometry to four Hg2+ and one Sn2+ atom. In the second Br1- site, Br1- is bonded in a 3-coordinate geometry to one Hg2+ and two equivalent Sn2+ atoms.« less
