Materials Data on PrCu3Pd2 by Materials Project
PrCu3Pd2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Pr is bonded in a 10-coordinate geometry to six equivalent Pd and ten Cu atoms. There are four shorter (3.02 Å) and two longer (3.03 Å) Pr–Pd bond lengths. There are a spread of Pr–Cu bond distances ranging from 3.06–3.27 Å. Pd is bonded to three equivalent Pr, two equivalent Pd, and seven Cu atoms to form a mixture of distorted corner, edge, and face-sharing PdPr3Cu7Pd2 cuboctahedra. There are one shorter (2.72 Å) and one longer (2.76 Å) Pd–Pd bond lengths. There are a spread of Pd–Cu bond distances ranging from 2.58–3.11 Å. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent Pr, four equivalent Pd, and five Cu atoms. There are a spread of Cu–Cu bond distances ranging from 2.50–3.18 Å. In the second Cu site, Cu is bonded in a 12-coordinate geometry to four equivalent Pr, six equivalent Pd, and six equivalent Cu atoms.
