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.
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. All Yb(1)-Au(1) bond lengths are 3.02 Å. All Yb(1)-Cu(1) bond lengths are 2.89 Å. Au(1) is bonded in a 16-coordinate geometry to four equivalent Yb(1) and twelve equivalent Cu(1) atoms. All Au(1)-Cu(1) bond lengths are 2.89 Å. 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. There are three shorter (2.46 Å) and three longer (2.47 Å) Cu(1)-Cu(1) bond lengths.
