Materials Data on SrMg by Materials Project

Abstract

SrMg crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 12-coordinate geometry to four equivalent Sr and eight Mg atoms. There are two shorter (3.87 Å) and two longer (3.98 Å) Sr–Sr bond lengths. There are a spread of Sr–Mg bond distances ranging from 3.58–3.93 Å. In the second Sr site, Sr is bonded in a 12-coordinate geometry to five Sr and seven Mg atoms. There are one shorter (3.69 Å) and two longer (3.77 Å) Sr–Sr bond lengths. There are a spread of Sr–Mg bond distances ranging from 3.61–3.89 Å. There are two inequivalent Mg sites. In the first Mg site, Mg is bonded in a 7-coordinate geometry to seven Sr atoms. In the second Mg site, Mg is bonded in a 8-coordinate geometry to eight Sr atoms.
