The compound described by HoCu5 crystallizes in the hexagonal P6/mmm space group. Ho(1) is bonded in a distorted hexagonal planar geometry to six equivalent Cu(1) and twelve equivalent Cu(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to three equivalent Ho(1) and six equivalent Cu(2) atoms. In the second Cu site, Cu(2) is bonded to four equivalent Ho(1), four equivalent Cu(1), and four equivalent Cu(2) atoms to form a mixture of corner, edge, and face-sharing CuHo4Cu8 cuboctahedra. is represented by the CIF card [CIF]
