Materials Data on Eu3Ho by Materials Project

Abstract

HoEu3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ho is bonded to twelve equivalent Eu atoms to form HoEu12 cuboctahedra that share corners with six equivalent HoEu12 cuboctahedra, corners with twelve equivalent EuEu8Ho4 cuboctahedra, edges with eighteen equivalent EuEu8Ho4 cuboctahedra, faces with eight equivalent HoEu12 cuboctahedra, and faces with twelve equivalent EuEu8Ho4 cuboctahedra. There are six shorter (3.75 Å) and six longer (3.82 Å) Ho–Eu bond lengths. Eu is bonded to four equivalent Ho and eight equivalent Eu atoms to form EuEu8Ho4 cuboctahedra that share corners with four equivalent HoEu12 cuboctahedra, corners with fourteen equivalent EuEu8Ho4 cuboctahedra, edges with six equivalent HoEu12 cuboctahedra, edges with twelve equivalent EuEu8Ho4 cuboctahedra, faces with four equivalent HoEu12 cuboctahedra, and faces with sixteen equivalent EuEu8Ho4 cuboctahedra. There are a spread of Eu–Eu bond distances ranging from 3.74–3.90 Å.
