Materials Data on MgHg2 by Materials Project

MgHg2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one MgHg2 sheet oriented in the (0, 0, 1) direction. Mg is bonded in a 7-coordinate geometry to seven Hg atoms. There are a spread of Mg–Hg bond distances ranging from 2.93–3.15 Å. There are two inequivalent Hg sites. In the first Hg site, Hg is bonded in a 3-coordinate geometry to three equivalent Mg atoms. In the second Hg site, Hg is bonded in a 9-coordinate geometry to four equivalent Mg atoms.
