Materials Data on Mg3Bi by Materials Project

Abstract

Mg3Bi 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 Bi atoms to form distorted MgMg8Bi4 cuboctahedra that share corners with twelve equivalent MgMg8Bi4 cuboctahedra, edges with eight equivalent BiMg12 cuboctahedra, edges with sixteen equivalent MgMg8Bi4 cuboctahedra, faces with four equivalent BiMg12 cuboctahedra, and faces with fourteen equivalent MgMg8Bi4 cuboctahedra. All Mg–Mg bond lengths are 3.27 Å. All Mg–Bi bond lengths are 3.27 Å. Bi is bonded to twelve equivalent Mg atoms to form BiMg12 cuboctahedra that share corners with twelve equivalent BiMg12 cuboctahedra, edges with twenty-four equivalent MgMg8Bi4 cuboctahedra, faces with six equivalent BiMg12 cuboctahedra, and faces with twelve equivalent MgMg8Bi4 cuboctahedra.
