Cu is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to six equivalent Cu(1) and six equivalent Cu(2) atoms to form a mixture of edge, corner, and face-sharing CuCu12 cuboctahedra. In the second Cu site, Cu(2) is bonded to six equivalent Cu(1) and six equivalent Cu(2) atoms to form a mixture of edge, corner, and face-sharing CuCu12 cuboctahedra.

In the first Cu site, Cu(1) is bonded to six equivalent Cu(1) and six equivalent Cu(2) atoms to form a mixture of edge, corner, and face-sharing CuCu12 cuboctahedra. All Cu(1)-Cu(1) bond lengths are 2.53 Å. All Cu(1)-Cu(2) bond lengths are 2.53 Å. In the second Cu site, Cu(2) is bonded to six equivalent Cu(1) and six equivalent Cu(2) atoms to form a mixture of edge, corner, and face-sharing CuCu12 cuboctahedra. All Cu(2)-Cu(2) bond lengths are 2.53 Å.
