Materials Data on Eu3Au2 by Materials Project
Eu3Au2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are three inequivalent Eu sites. In the first Eu site, Eu is bonded in an octahedral geometry to six equivalent Au atoms. All Eu–Au bond lengths are 3.23 Å. In the second Eu site, Eu is bonded in a 6-coordinate geometry to six equivalent Au atoms. There are three shorter (3.11 Å) and three longer (3.30 Å) Eu–Au bond lengths. In the third Eu site, Eu is bonded in a 5-coordinate geometry to five equivalent Au atoms. There are a spread of Eu–Au bond distances ranging from 3.15–3.48 Å. Au is bonded in a 8-coordinate geometry to eight Eu atoms.
