Title: Materials Data on Sr3Mg by Materials Project

Abstract

Sr3Mg is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded to eight equivalent Sr and four equivalent Mg atoms to form distorted SrSr8Mg4 cuboctahedra that share corners with four equivalent SrSr8Mg4 cuboctahedra, corners with eight equivalent MgSr12 cuboctahedra, edges with twenty-four SrSr8Mg4 cuboctahedra, faces with six equivalent MgSr12 cuboctahedra, and faces with twelve SrSr8Mg4 cuboctahedra. All Sr–Sr bond lengths are 4.05 Å. All Sr–Mg bond lengths are 3.91 Å. In the second Sr site, Sr is bonded to eight Sr and four equivalent Mg atoms to form SrSr8Mg4 cuboctahedra that share corners with twelve equivalent SrSr8Mg4 cuboctahedra, edges with eight equivalent MgSr12 cuboctahedra, edges with sixteen SrSr8Mg4 cuboctahedra, faces with four equivalent MgSr12 cuboctahedra, and faces with fourteen SrSr8Mg4 cuboctahedra. All Sr–Sr bond lengths are 3.91 Å. All Sr–Mg bond lengths are 4.05 Å. Mg is bonded to twelve Sr atoms to form MgSr12 cuboctahedra that share corners with four equivalent MgSr12 cuboctahedra, corners with eight equivalent SrSr8Mg4 cuboctahedra, edges with eight equivalent MgSr12 cuboctahedra, edges with sixteen equivalent SrSr8Mg4 cuboctahedra, faces with four equivalent MgSr12 cuboctahedra, and facesmore » with fourteen SrSr8Mg4 cuboctahedra.« less
