Materials Data on Mg5Hg by Materials Project
Mg5Hg crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent Mg sites. In the first Mg site, Mg is bonded to ten Mg and two equivalent Hg atoms to form distorted MgMg10Hg2 cuboctahedra that share corners with eighteen equivalent MgMg10Hg2 cuboctahedra, edges with four equivalent HgMg12 cuboctahedra, edges with fourteen MgMg10Hg2 cuboctahedra, faces with four equivalent HgMg12 cuboctahedra, and faces with sixteen MgMg10Hg2 cuboctahedra. There are a spread of Mg–Mg bond distances ranging from 3.07–3.18 Å. Both Mg–Hg bond lengths are 3.16 Å. In the second Mg site, Mg is bonded to nine Mg and three equivalent Hg atoms to form distorted MgMg9Hg3 cuboctahedra that share corners with nine equivalent MgMg9Hg3 cuboctahedra, corners with nine equivalent HgMg12 cuboctahedra, edges with eighteen MgMg10Hg2 cuboctahedra, faces with three equivalent HgMg12 cuboctahedra, and faces with seventeen MgMg10Hg2 cuboctahedra. All Mg–Mg bond lengths are 3.12 Å. All Mg–Hg bond lengths are 3.12 Å. Hg is bonded to twelve Mg atoms to form HgMg12 cuboctahedra that share corners with eighteen equivalent MgMg9Hg3 cuboctahedra, edges with six equivalent HgMg12 cuboctahedra, edges with twelve equivalent MgMg10Hg2 cuboctahedra, faces with two equivalent HgMg12 cuboctahedra, and faces with eighteen MgMg10Hg2 cuboctahedra.
