The material described by YbAuCu4 crystallizes in the cubic F-43m space group. Yb(1) is bonded in a 16-coordinate geometry to four equivalent Au(1) and twelve equivalent Cu(1) atoms. Au(1) is bonded in a 16-coordinate geometry to four equivalent Yb(1) and twelve equivalent Cu(1) atoms. Cu(1) is bonded to three equivalent Yb(1), three equivalent Au(1), and six equivalent Cu(1) atoms to form a mixture of corner, face, and edge-sharing CuYb3Cu6Au3 cuboctahedra. is represented by the CIF file [CIF]
