Abstract

MgHg2 is Titanium Disilicide structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Mg is bonded in a distorted q6 geometry to ten equivalent Hg atoms. There are a spread of Mg–Hg bond distances ranging from 3.06–3.25 Å. Hg is bonded in a 5-coordinate geometry to five equivalent Mg atoms.
