Materials Data on Eu(In4Ir)2 by Materials Project

Abstract

Eu(IrIn4)2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Eu is bonded in a 10-coordinate geometry to thirteen In atoms. There are a spread of Eu–In bond distances ranging from 3.47–3.88 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 9-coordinate geometry to nine In atoms. There are a spread of Ir–In bond distances ranging from 2.69–2.97 Å. In the second Ir site, Ir is bonded in a 9-coordinate geometry to nine In atoms. There are a spread of Ir–In bond distances ranging from 2.72–3.02 Å. There are nine inequivalent In sites. In the first In site, In is bonded in a 4-coordinate geometry to four equivalent Ir atoms. In the second In site, In is bonded in a linear geometry to two equivalent Eu, two equivalent Ir, and four equivalent In atoms. All In–In bond lengths are 3.17 Å. In the third In site, In is bonded in a 4-coordinate geometry to two equivalent Eu, two equivalent Ir, and eight In atoms. There are a spread of In–In bond distances ranging from 3.22–3.38 Å. In the fourth In site, In is bonded in a 2-coordinate geometry to two equivalent Eu, two equivalent Ir, and one In atom. The In–In bond length is 2.99 Å. In the fifth In site, In is bonded in a 2-coordinate geometry to two equivalent Eu, two equivalent Ir, and one In atom. In the sixth In site, In is bonded in a 2-coordinate geometry to two equivalent Eu, two equivalent Ir, and three In atoms. In the seventh In site, In is bonded in a 2-coordinate geometry to two equivalent Eu, two equivalent Ir, and one In atom. In the eighth In site, In is bonded in a distorted linear geometry to two equivalent Eu, two Ir, and two equivalent In atoms. In the ninth In site, In is bonded in a 1-coordinate geometry to three Ir atoms.
