Materials Data on Mg3Cd by Materials Project

Abstract

Mg3Cd 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 Cd atoms to form MgMg8Cd4 cuboctahedra that share corners with twelve equivalent MgMg8Cd4 cuboctahedra, edges with eight equivalent CdMg12 cuboctahedra, edges with sixteen equivalent MgMg8Cd4 cuboctahedra, faces with four equivalent CdMg12 cuboctahedra, and faces with fourteen equivalent MgMg8Cd4 cuboctahedra. All Mg–Mg bond lengths are 3.15 Å. All Mg–Cd bond lengths are 3.15 Å. Cd is bonded to twelve equivalent Mg atoms to form CdMg12 cuboctahedra that share corners with twelve equivalent CdMg12 cuboctahedra, edges with twenty-four equivalent MgMg8Cd4 cuboctahedra, faces with six equivalent CdMg12 cuboctahedra, and faces with twelve equivalent MgMg8Cd4 cuboctahedra.
