Materials Data on Ce(SnPd)2 by Materials Project

Abstract

Ce(PdSn)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce is bonded in a 12-coordinate geometry to eight Pd and eight Sn atoms. There are four shorter (3.46 Å) and four longer (3.54 Å) Ce–Pd bond lengths. There are four shorter (3.49 Å) and four longer (3.56 Å) Ce–Sn bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 4-coordinate geometry to four equivalent Ce and four equivalent Sn atoms. All Pd–Sn bond lengths are 2.67 Å. In the second Pd site, Pd is bonded in a 9-coordinate geometry to four equivalent Ce and five Sn atoms. There are one shorter (2.60 Å) and four longer (2.68 Å) Pd–Sn bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 4-coordinate geometry to four equivalent Ce and four equivalent Pd atoms. In the second Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent Ce and five Pd atoms.
