Materials Data on GdCu4Pd by Materials Project

Abstract

GdPdCu4 crystallizes in the trigonal R3m space group. The structure is three-dimensional. Gd is bonded in a 3-coordinate geometry to three equivalent Pd and thirteen Cu atoms. All Gd–Pd bond lengths are 2.95 Å. There are a spread of Gd–Cu bond distances ranging from 2.99–3.18 Å. Pd is bonded to three equivalent Gd and nine Cu atoms to form a mixture of edge and corner-sharing PdGd3Cu9 cuboctahedra. There are a spread of Pd–Cu bond distances ranging from 2.56–2.95 Å. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent Gd, two equivalent Pd, and seven Cu atoms. There are a spread of Cu–Cu bond distances ranging from 2.50–3.08 Å. In the second Cu site, Cu is bonded in a 7-coordinate geometry to four equivalent Gd, three equivalent Pd, and nine equivalent Cu atoms.
