Title: Materials Data on Sr2Mg by Materials Project

Abstract

Sr2Mg1 crystallizes in the trigonal R32 space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded to eight Sr and four equivalent Mg atoms to form a mixture of distorted face, edge, and corner-sharing SrSr8Mg4 cuboctahedra. There are a spread of Sr–Sr bond distances ranging from 3.90–4.01 Å. There are two shorter (3.90 Å) and two longer (3.94 Å) Sr–Mg bond lengths. In the second Sr site, Sr is bonded to six equivalent Sr and six equivalent Mg atoms to form SrSr6Mg6 cuboctahedra that share corners with six equivalent SrSr6Mg6 cuboctahedra, edges with eighteen SrSr8Mg4 cuboctahedra, and faces with twelve equivalent SrSr8Mg4 cuboctahedra. All Sr–Mg bond lengths are 3.97 Å. Mg is bonded in a 9-coordinate geometry to nine Sr atoms.
