Materials Data on CeYMg4 by Materials Project

Abstract

Mg4CeY is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Mg is bonded to six equivalent Mg, three equivalent Ce, and three equivalent Y atoms to form a mixture of edge, face, and corner-sharing MgCe3Y3Mg6 cuboctahedra. There are three shorter (3.01 Å) and three longer (3.02 Å) Mg–Mg bond lengths. All Mg–Ce bond lengths are 3.54 Å. All Mg–Y bond lengths are 3.54 Å. Ce is bonded in a 12-coordinate geometry to twelve equivalent Mg and four equivalent Y atoms. All Ce–Y bond lengths are 3.69 Å. Y is bonded in a 12-coordinate geometry to twelve equivalent Mg and four equivalent Ce atoms.
