The material described by LuCu5 crystallizes in the cubic F-43m space group. Lu(1) is bonded in a 16-coordinate geometry to four equivalent Cu(2) and twelve equivalent Cu(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to three equivalent Lu(1), three equivalent Cu(2), and six equivalent Cu(1) atoms to form a mixture of distorted edge, face, and corner-sharing CuLu3Cu9 cuboctahedra. In the second Cu site, Cu(2) is bonded in a 16-coordinate geometry to four equivalent Lu(1) and twelve equivalent Cu(1) atoms. is represented by the CIF card [CIF]
