Materials Data on Eu(In2Ag)4 by Materials Project

Abstract

EuAg4In8 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to eight equivalent Ag and twelve In atoms. All Eu–Ag bond lengths are 4.07 Å. There are four shorter (3.69 Å) and eight longer (3.84 Å) Eu–In bond lengths. Ag is bonded in a 12-coordinate geometry to two equivalent Eu, two equivalent Ag, and eight In atoms. Both Ag–Ag bond lengths are 3.11 Å. There are four shorter (3.11 Å) and four longer (3.25 Å) Ag–In bond lengths. There are two inequivalent In sites. In the first In site, In is bonded in a 10-coordinate geometry to one Eu, four equivalent Ag, and five In atoms. There are a spread of In–In bond distances ranging from 3.25–3.47 Å. In the second In site, In is bonded in a 12-coordinate geometry to two equivalent Eu, four equivalent Ag, and six In atoms. Both In–In bond lengths are 3.19 Å.
