Materials Data on LaHg2 by Materials Project

LaHg2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. La is bonded to twelve equivalent Hg atoms to form a mixture of distorted edge and face-sharing LaHg12 cuboctahedra. There are a spread of La–Hg bond distances ranging from 3.43–3.48 Å. Hg is bonded in a 9-coordinate geometry to six equivalent La and three equivalent Hg atoms. There are one shorter (2.94 Å) and two longer (2.96 Å) Hg–Hg bond lengths.
