Materials Data on Mg3Sn by Materials Project

Abstract

Mg3Sn is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mg is bonded to eight equivalent Mg and four equivalent Sn atoms to form distorted MgMg8Sn4 cuboctahedra that share corners with twelve equivalent MgMg8Sn4 cuboctahedra, edges with eight equivalent SnMg12 cuboctahedra, edges with sixteen equivalent MgMg8Sn4 cuboctahedra, faces with four equivalent SnMg12 cuboctahedra, and faces with fourteen equivalent MgMg8Sn4 cuboctahedra. All Mg–Mg bond lengths are 3.18 Å. All Mg–Sn bond lengths are 3.18 Å. Sn is bonded to twelve equivalent Mg atoms to form SnMg12 cuboctahedra that share corners with twelve equivalent SnMg12 cuboctahedra, edges with twenty-four equivalent MgMg8Sn4 cuboctahedra, faces with six equivalent SnMg12 cuboctahedra, and faces with twelve equivalent MgMg8Sn4 cuboctahedra.
