Materials Data on Sr3Mg by Materials Project

Abstract

Sr3Mg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Sr is bonded to eight equivalent 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 equivalent SrSr8Mg4 cuboctahedra, faces with four equivalent MgSr12 cuboctahedra, and faces with fourteen equivalent SrSr8Mg4 cuboctahedra. All Sr–Sr bond lengths are 4.00 Å. All Sr–Mg bond lengths are 4.00 Å. Mg is bonded to twelve equivalent Sr atoms to form MgSr12 cuboctahedra that share corners with twelve equivalent MgSr12 cuboctahedra, edges with twenty-four equivalent SrSr8Mg4 cuboctahedra, faces with six equivalent MgSr12 cuboctahedra, and faces with twelve equivalent SrSr8Mg4 cuboctahedra.
