Materials Data on LuCu5 by Materials Project
LuCu5 crystallizes in the cubic F-43m space group. The structure is three-dimensional. Lu is bonded in a 12-coordinate geometry to sixteen Cu atoms. There are twelve shorter (2.89 Å) and four longer (3.02 Å) Lu–Cu bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded to three equivalent Lu and nine Cu atoms to form a mixture of distorted face, edge, and corner-sharing CuLu3Cu9 cuboctahedra. There are a spread of Cu–Cu bond distances ranging from 2.45–2.89 Å. In the second Cu site, Cu is bonded in a 4-coordinate geometry to four equivalent Lu and twelve equivalent Cu atoms.
