Title: Materials Data on CeEr by Materials Project

Abstract

ErCe is beta-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are five inequivalent Er sites. In the first Er site, Er is bonded to nine Er and three equivalent Ce atoms to form ErCe3Er9 cuboctahedra that share corners with six equivalent CeCe9Er3 cuboctahedra, corners with nine ErCe3Er9 cuboctahedra, edges with six equivalent CeCe6Er6 cuboctahedra, edges with fifteen ErCe6Er6 cuboctahedra, faces with seven CeCe9Er3 cuboctahedra, and faces with twelve ErCe3Er9 cuboctahedra. There are three shorter (3.48 Å) and six longer (3.55 Å) Er–Er bond lengths. All Er–Ce bond lengths are 3.46 Å. In the second Er site, Er is bonded to six equivalent Er and six Ce atoms to form ErCe6Er6 cuboctahedra that share corners with six equivalent CeCe9Er3 cuboctahedra, corners with nine ErCe3Er9 cuboctahedra, edges with nine ErCe3Er9 cuboctahedra, edges with twelve CeCe9Er3 cuboctahedra, faces with six equivalent ErCe6Er6 cuboctahedra, and faces with thirteen CeCe9Er3 cuboctahedra. All Er–Er bond lengths are 3.55 Å. There are three shorter (3.44 Å) and three longer (3.50 Å) Er–Ce bond lengths.
