Materials Data on EuEr by Materials Project

Abstract

ErEu is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Er is bonded to six equivalent Er and six equivalent Eu atoms to form ErEu6Er6 cuboctahedra that share corners with eighteen equivalent ErEu6Er6 cuboctahedra, edges with six equivalent ErEu6Er6 cuboctahedra, edges with twelve equivalent EuEu6Er6 cuboctahedra, faces with eight equivalent ErEu6Er6 cuboctahedra, and faces with twelve equivalent EuEu6Er6 cuboctahedra. All Er–Er bond lengths are 3.66 Å. All Er–Eu bond lengths are 3.69 Å.
