Materials Data on CeMg3 by Materials Project

Abstract

Mg3Ce 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 Ce atoms to form MgCe4Mg8 cuboctahedra that share corners with twelve equivalent MgCe4Mg8 cuboctahedra, edges with eight equivalent CeMg12 cuboctahedra, edges with sixteen equivalent MgCe4Mg8 cuboctahedra, faces with four equivalent CeMg12 cuboctahedra, and faces with fourteen equivalent MgCe4Mg8 cuboctahedra. All Mg–Mg bond lengths are 3.38 Å. All Mg–Ce bond lengths are 3.38 Å. Ce is bonded to twelve equivalent Mg atoms to form CeMg12 cuboctahedra that share corners with twelve equivalent CeMg12 cuboctahedra, edges with twenty-four equivalent MgCe4Mg8 cuboctahedra, faces with six equivalent CeMg12 cuboctahedra, and faces with twelve equivalent MgCe4Mg8 cuboctahedra.
