Materials Data on SnHg2(SBr)2 by Materials Project
Hg2Sn(SBr)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Hg2Sn(SBr)2 sheet oriented in the (1, 0, 0) direction. there are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a T-shaped geometry to two S2- and one Br1- atom. There are one shorter (2.37 Å) and one longer (2.40 Å) Hg–S bond lengths. The Hg–Br bond length is 3.24 Å. In the second Hg2+ site, Hg2+ is bonded in a 3-coordinate geometry to two equivalent S2- and one Br1- atom. There are one shorter (3.53 Å) and one longer (3.59 Å) Hg–S bond lengths. The Hg–Br bond length is 3.69 Å. Sn2+ is bonded in a tetrahedral geometry to two S2- and two Br1- atoms. There are one shorter (2.39 Å) and one longer (2.43 Å) Sn–S bond lengths. There are one shorter (2.52 Å) and one longer (2.54 Å) Sn–Br bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a bent 120 degrees geometry to one Hg2+ and one Sn2+ atom. In the second S2- site, S2- is bonded in a distorted L-shaped geometry to three Hg2+ and one Sn2+ atom. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Hg2+ and one Sn2+ atom. In the second Br1- site, Br1- is bonded in a 1-coordinate geometry to one Hg2+ and one Sn2+ atom.
