Materials Data on UCu4Pd by Materials Project

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.

Materials Data on UCu3Pd2 by Materials Project

UPd2Cu3 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. U is bonded in a 6-coordinate geometry to six equivalent Pd and ten Cu atoms. There are four shorter (2.96 Å) and two longer (2.99 Å) U–Pd bond lengths. There are a spread of U–Cu bond distances ranging from 3.01–3.22 Å. Pd is bonded to three equivalent U, two equivalent Pd, and seven Cu atoms to form a mixture of distorted face, edge, and corner-sharing PdU3Cu7Pd2 cuboctahedra. There are one shorter (2.68 Å) and one longer (2.70 Å) Pd–Pd bond lengths. There are a spread of Pd–Cu bond distances ranging from 2.55–3.06 Å. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent U, four equivalent Pd, and five Cu atoms. There are a spread of Cu–Cu bond distances ranging from 2.46–3.11 Å. In the second Cu site, Cu is bonded in a 12-coordinate geometry to four equivalent U, six equivalent Pd, and six equivalent Cu atoms.
