Materials Data on CeCu5 by Materials Project
CeCu5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Ce is bonded in a 6-coordinate geometry to eighteen Cu atoms. There are six shorter (2.93 Å) and twelve longer (3.27 Å) Ce–Cu bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded to four equivalent Ce and eight Cu atoms to form a mixture of corner, edge, and face-sharing CuCe4Cu8 cuboctahedra. There are four shorter (2.52 Å) and four longer (2.54 Å) Cu–Cu bond lengths. In the second Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent Ce and six equivalent Cu atoms.
