Title: Materials Data on Ce3Mg by Materials Project

Abstract

MgCe3 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Mg is bonded to six equivalent Mg and six equivalent Ce atoms to form MgCe6Mg6 cuboctahedra that share corners with six equivalent MgCe6Mg6 cuboctahedra, corners with twelve equivalent CeCe12 cuboctahedra, edges with six equivalent MgCe6Mg6 cuboctahedra, edges with twelve equivalent CeCe9Mg3 cuboctahedra, faces with six equivalent MgCe6Mg6 cuboctahedra, and faces with fourteen CeCe12 cuboctahedra. All Mg–Mg bond lengths are 3.19 Å. All Mg–Ce bond lengths are 3.46 Å. There are two inequivalent Ce sites. In the first Ce site, Ce is bonded to twelve Ce atoms to form CeCe12 cuboctahedra that share corners with six equivalent CeCe12 cuboctahedra, corners with twelve equivalent MgCe6Mg6 cuboctahedra, edges with eighteen CeCe12 cuboctahedra, faces with two equivalent MgCe6Mg6 cuboctahedra, and faces with eighteen CeCe12 cuboctahedra. There are six shorter (3.19 Å) and six longer (3.48 Å) Ce–Ce bond lengths. In the second Ce site, Ce is bonded to three equivalent Mg and nine Ce atoms to form CeCe9Mg3 cuboctahedra that share corners with eighteen equivalent CeCe9Mg3 cuboctahedra, edges with six equivalent MgCe6Mg6 cuboctahedra, edges with twelve CeCe12 cuboctahedra, faces with six equivalent MgCe6Mg6 cuboctahedra, and faces with fourteen CeCe12 cuboctahedra.
