Materials Data on Eu5Ga3 by Materials Project

Abstract

Eu5Ga3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Eu sites. In the first Eu site, Eu is bonded in a 6-coordinate geometry to six Ga atoms. There are two shorter (3.17 Å) and four longer (3.39 Å) Eu–Ga bond lengths. In the second Eu site, Eu is bonded in a 6-coordinate geometry to six Ga atoms. There are a spread of Eu–Ga bond distances ranging from 3.27–3.56 Å. In the third Eu site, Eu is bonded in a 4-coordinate geometry to four Ga atoms. There are a spread of Eu–Ga bond distances ranging from 3.20–3.36 Å. In the fourth Eu site, Eu is bonded in a 4-coordinate geometry to four Ga atoms. There are a spread of Eu–Ga bond distances ranging from 3.24–3.33 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 9-coordinate geometry to eight Eu and one Ga atom. The Ga–Ga bond length is 2.76 Å. In the second Ga site, Ga is bonded in a 8-coordinate geometry to eight Eu atoms.
