Materials Data on Hg2Br2N by Materials Project

Abstract

Hg2NBr2 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are three inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded to five Br1- atoms to form corner-sharing HgBr5 trigonal bipyramids. There are a spread of Hg–Br bond distances ranging from 2.63–3.12 Å. In the second Hg2+ site, Hg2+ is bonded in a distorted linear geometry to two equivalent N2- and four Br1- atoms. Both Hg–N bond lengths are 2.08 Å. There are a spread of Hg–Br bond distances ranging from 3.26–3.62 Å. In the third Hg2+ site, Hg2+ is bonded in a distorted linear geometry to two equivalent N2- and four Br1- atoms. Both Hg–N bond lengths are 2.08 Å. There are a spread of Hg–Br bond distances ranging from 3.26–3.62 Å. N2- is bonded in a trigonal planar geometry to three Hg2+ atoms. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded to eight Hg2+ atoms to form distorted corner-sharing BrHg8 hexagonal bipyramids. In the second Br1- site, Br1- is bonded in a 1-coordinate geometry to three Hg2+ atoms. In the third Br1- site, Br1- is bonded in a 1-coordinate geometry to three Hg2+ atoms.
