Title: Materials Data on EuCu9Sn4 by Materials Project

Abstract

EuCu9Sn4 is Bergman Structure: Mg32(Al,Zn)49 Bergman-like structured and crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. Eu is bonded in a 8-coordinate geometry to sixteen Cu and eight equivalent Sn atoms. There are eight shorter (3.60 Å) and eight longer (3.65 Å) Eu–Cu bond lengths. All Eu–Sn bond lengths are 3.52 Å. There are three inequivalent Cu sites. In the first Cu site, Cu is bonded in a 12-coordinate geometry to two equivalent Eu, six Cu, and four equivalent Sn atoms. There are a spread of Cu–Cu bond distances ranging from 2.54–2.76 Å. There are a spread of Cu–Sn bond distances ranging from 2.60–2.70 Å. In the second Cu site, Cu is bonded in a 12-coordinate geometry to two equivalent Eu, six Cu, and four equivalent Sn atoms. There are a spread of Cu–Cu bond distances ranging from 2.56–2.99 Å. There are two shorter (2.75 Å) and two longer (2.79 Å) Cu–Sn bond lengths. In the third Cu site, Cu is bonded in a cuboctahedral geometry to eight Cu and four equivalent Sn atoms. All Cu–Sn bond lengths are 2.77 Å. Sn is bonded in a 11-coordinate geometry to two equivalent Eu and nine Cu atoms.
