Materials Data on UCu4Pd by Materials Project

Abstract

UCu4Pd is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. U is bonded in a 12-coordinate geometry to four equivalent Pd and twelve equivalent Cu atoms. All U–Pd bond lengths are 3.05 Å. All U–Cu bond lengths are 2.92 Å. Pd is bonded in a 4-coordinate geometry to four equivalent U and twelve equivalent Cu atoms. All Pd–Cu bond lengths are 2.92 Å. Cu is bonded to three equivalent U, three equivalent Pd, and six equivalent Cu atoms to form a mixture of face, edge, and corner-sharing CuU3Cu6Pd3 cuboctahedra. There are three shorter (2.48 Å) and three longer (2.51 Å) Cu–Cu bond lengths.
