Materials Data on Mg5Hg3 by Materials Project
Mg5Hg3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a 5-coordinate geometry to five equivalent Hg atoms. There are a spread of Mg–Hg bond distances ranging from 2.85–3.14 Å. In the second Mg site, Mg is bonded in a 6-coordinate geometry to six equivalent Hg atoms. All Mg–Hg bond lengths are 2.98 Å. Hg is bonded in a 9-coordinate geometry to nine Mg atoms.
