Materials Data on Eu2GaAg3 by Materials Project

Abstract

Eu2Ag3Ga crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Eu sites. In the first Eu site, Eu is bonded in a 12-coordinate geometry to nine Ag and three equivalent Ga atoms. There are a spread of Eu–Ag bond distances ranging from 3.21–3.52 Å. There are one shorter (3.32 Å) and two longer (3.53 Å) Eu–Ga bond lengths. In the second Eu site, Eu is bonded in a 12-coordinate geometry to nine Ag and three equivalent Ga atoms. There are a spread of Eu–Ag bond distances ranging from 3.24–3.52 Å. There are one shorter (3.31 Å) and two longer (3.32 Å) Eu–Ga bond lengths. There are three inequivalent Ag sites. In the first Ag site, Ag is bonded in a 10-coordinate geometry to six Eu, three Ag, and one Ga atom. There are two shorter (2.85 Å) and one longer (3.00 Å) Ag–Ag bond lengths. The Ag–Ga bond length is 2.72 Å. In the second Ag site, Ag is bonded in a 10-coordinate geometry to six Eu, two Ag, and two equivalent Ga atoms. The Ag–Ag bond length is 2.85 Å. Both Ag–Ga bond lengths are 2.72 Å. In the third Ag site, Ag is bonded in a 10-coordinate geometry to six Eu, three Ag, and one Ga atom. The Ag–Ga bond length is 2.80 Å. Ga is bonded in a 10-coordinate geometry to six Eu and four Ag atoms.
