Abstract
(Mg)298H2 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional and consists of one hydrogen molecule and one Mg framework. In the Mg framework, there are twenty-seven inequivalent Mg sites. In the first Mg site, Mg is bonded in a 11-coordinate geometry to seven Mg atoms. There are a spread of Mg–Mg bond distances ranging from 3.18–3.24 Å. In the second Mg site, Mg is bonded to twelve Mg atoms to form a mixture of edge, face, and corner-sharing MgMg12 cuboctahedra. There are eight shorter (3.19 Å) and two longer (3.20 Å) Mg–Mg bond lengths. In the third Mg site, Mg is bonded to twelve Mg atoms to form a mixture of edge, face, and corner-sharing MgMg12 cuboctahedra. All Mg–Mg bond lengths are 3.19 Å. In the fourth Mg site, Mg is bonded to twelve Mg atoms to form a mixture of edge, face, and corner-sharing MgMg12 cuboctahedra. There are six shorter (3.18 Å) and four longer (3.20 Å) Mg–Mg bond lengths. In the fifth Mg site, Mg is bonded to twelve Mg atoms to form a mixture of edge, face, and corner-sharing MgMg12 cuboctahedra. There are seven shorter (3.19 Å) and one longer (3.20 Å) Mg–Mg bondmore »
