Materials Data on Sr2Mg by Materials Project

Abstract

Sr2Mg1 is Khatyrkite structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 4-coordinate geometry to four equivalent Mg atoms. There are a spread of Sr–Mg bond distances ranging from 3.71–3.76 Å. In the second Sr site, Sr is bonded in a 4-coordinate geometry to four equivalent Mg atoms. There are two shorter (3.69 Å) and two longer (3.73 Å) Sr–Mg bond lengths. Mg is bonded in a 10-coordinate geometry to eight Sr and two equivalent Mg atoms. There are one shorter (3.38 Å) and one longer (3.39 Å) Mg–Mg bond lengths.
