Materials Data on Hg2I3Br by Materials Project
HgI2HgBrI crystallizes in the monoclinic Cm space group. The structure is two-dimensional and consists of two 13444-76-3 molecules and one HgI2 sheet oriented in the (0, 0, 1) direction. In the HgI2 sheet, Hg2+ is bonded to six I1- atoms to form edge-sharing HgI6 octahedra. There are a spread of Hg–I bond distances ranging from 2.66–3.66 Å. There are two inequivalent I1- sites. In the first I1- site, I1- is bonded in a 1-coordinate geometry to three equivalent Hg2+ atoms. In the second I1- site, I1- is bonded in a 1-coordinate geometry to three equivalent Hg2+ atoms.
