Materials Data on SrMg2 by Materials Project
Abstract
Mg2Sr is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr is bonded in a 12-coordinate geometry to four equivalent Sr and twelve Mg atoms. There are three shorter (3.93 Å) and one longer (4.00 Å) Sr–Sr bond lengths. There are a spread of Sr–Mg bond distances ranging from 3.75–3.83 Å. There are two inequivalent Mg sites. In the first Mg site, Mg is bonded to six equivalent Sr and six equivalent Mg atoms to form a mixture of corner, edge, and face-sharing MgSr6Mg6 cuboctahedra. All Mg–Mg bond lengths are 3.26 Å. In the second Mg site, Mg is bonded to six equivalent Sr and six Mg atoms to form a mixture of corner, edge, and face-sharing MgSr6Mg6 cuboctahedra. There are two shorter (3.17 Å) and two longer (3.21 Å) Mg–Mg bond lengths.
