Materials Data on EuCu5 by Materials Project

EuCu5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Eu is bonded in a 6-coordinate geometry to eighteen Cu atoms. There are six shorter (2.98 Å) and twelve longer (3.28 Å) Eu–Cu bond lengths. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded to four equivalent Eu and eight Cu atoms to form a mixture of face, edge, and corner-sharing CuEu4Cu8 cuboctahedra. There are four shorter (2.51 Å) and four longer (2.58 Å) Cu–Cu bond lengths. In the second Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent Eu and six equivalent Cu atoms.
