Materials Data on HgSBr by Materials Project
HgSBr crystallizes in the monoclinic P2_1/m space group. The structure is one-dimensional and consists of one HgSBr ribbon oriented in the (0, 1, 0) direction. Hg2+ is bonded in a distorted rectangular see-saw-like geometry to one S1- and three equivalent Br1- atoms. The Hg–S bond length is 2.36 Å. There are one shorter (2.50 Å) and two longer (3.36 Å) Hg–Br bond lengths. S1- is bonded in a distorted single-bond geometry to one Hg2+ atom. Br1- is bonded in a 1-coordinate geometry to three equivalent Hg2+ atoms.
