Materials Data on Eu(CuSn)2 by Materials Project

Abstract

EuCu2Sn2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Eu is bonded in a 10-coordinate geometry to six equivalent Cu and four equivalent Sn atoms. There are two shorter (3.19 Å) and four longer (3.33 Å) Eu–Cu bond lengths. All Eu–Sn bond lengths are 3.47 Å. Cu is bonded in a 9-coordinate geometry to three equivalent Eu, two equivalent Cu, and four equivalent Sn atoms. Both Cu–Cu bond lengths are 2.60 Å. There are a spread of Cu–Sn bond distances ranging from 2.61–2.68 Å. Sn is bonded in a 9-coordinate geometry to two equivalent Eu, four equivalent Cu, and one Sn atom. The Sn–Sn bond length is 3.05 Å.
