Materials Data on SnHg2(SBr)2 by Materials Project
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 distorted T-shaped geometry to two S2- and one Br1- atom. There are one shorter (2.36 Å) and one longer (2.38 Å) Hg–S bond lengths. The Hg–Br bond length is 3.38 Å. In the second Hg2+ site, Hg2+ is bonded in a distorted rectangular see-saw-like geometry to three S2- and one Br1- atom. There are a spread of Hg–S bond distances ranging from 2.38–3.25 Å. The Hg–Br bond length is 3.43 Å. Sn2+ is bonded to one S2- and three Br1- atoms to form distorted edge-sharing SnSBr3 trigonal pyramids. The Sn–S bond length is 2.91 Å. There are a spread of Sn–Br bond distances ranging from 2.68–3.03 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 3-coordinate geometry to three Hg2+ atoms. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 1-coordinate geometry to two Hg2+ and one Sn2+ atom. In the second Br1- site, Br1- is bonded in a distorted L-shaped geometry to two equivalent Sn2+ atoms.
