Materials Data on Eu3(SnPd)2 by Materials Project

Abstract

Eu3Pd2Sn2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Eu sites. In the first Eu site, Eu is bonded in a 7-coordinate geometry to four equivalent Pd and five Sn atoms. There are a spread of Eu–Pd bond distances ranging from 3.06–3.48 Å. There are a spread of Eu–Sn bond distances ranging from 3.34–3.67 Å. In the second Eu site, Eu is bonded in a 9-coordinate geometry to four equivalent Pd and five Sn atoms. There are two shorter (3.37 Å) and two longer (3.38 Å) Eu–Pd bond lengths. There are a spread of Eu–Sn bond distances ranging from 3.26–3.52 Å. Pd is bonded in a 10-coordinate geometry to six Eu, one Pd, and three Sn atoms. The Pd–Pd bond length is 2.94 Å. There are a spread of Pd–Sn bond distances ranging from 2.73–2.79 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded to eight Eu and four equivalent Pd atoms to form a mixture of distorted face, edge, and corner-sharing SnEu8Pd4 cuboctahedra. In the second Sn site, Sn is bonded in a 9-coordinate geometry to seven Eu and two equivalent Pd atoms.
