Materials Data on ZrCu5 by Materials Project

Abstract

Cu5Zr crystallizes in the cubic F-43m space group. The structure is three-dimensional. Zr is bonded in a 12-coordinate geometry to sixteen Cu atoms. There are twelve shorter (2.84 Å) and four longer (2.96 Å) Zr–Cu bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 4-coordinate geometry to four equivalent Zr and twelve equivalent Cu atoms. All Cu–Cu bond lengths are 2.83 Å. In the second Cu site, Cu is bonded to three equivalent Zr and nine Cu atoms to form a mixture of distorted face, edge, and corner-sharing CuZr3Cu9 cuboctahedra. There are three shorter (2.41 Å) and three longer (2.43 Å) Cu–Cu bond lengths.
