NdCu5 crystallizes in the hexagonal P6/mmm space group. Nd(1) is bonded in a 18-coordinate 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 Nd(1) and six equivalent Cu(2) atoms. In the second Cu site, Cu(2) is bonded to four equivalent Nd(1), four equivalent Cu(1), and four equivalent Cu(2) atoms to form a mixture of edge, face, and corner-sharing CuNd4Cu8 cuboctahedra.
