Materials Data on Ce(Sn2Pd)2 by Materials Project

Abstract

CePd2Sn4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 8-coordinate geometry to four equivalent Pd and ten Sn atoms. All Ce–Pd bond lengths are 3.53 Å. There are a spread of Ce–Sn bond distances ranging from 3.40–3.55 Å. Pd is bonded in a 6-coordinate geometry to two equivalent Ce and six Sn atoms. There are a spread of Pd–Sn bond distances ranging from 2.74–2.82 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to four equivalent Ce, two equivalent Pd, and two Sn atoms. There are one shorter (2.87 Å) and one longer (3.03 Å) Sn–Sn bond lengths. In the second Sn site, Sn is bonded in a 6-coordinate geometry to one Ce, four equivalent Pd, and one Sn atom.
