The compound described by YbNiCu4 crystallizes in the cubic F-43m space group. Yb(1) is bonded in a 16-coordinate geometry to four equivalent Ni(1) and twelve equivalent Cu(1) atoms. Ni(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 Ni(1), and six equivalent Cu(1) atoms to form a mixture of distorted edge, corner, and face-sharing CuYb3Cu6Ni3 cuboctahedra. is represented by the CIF file [CIF]
