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.
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. All Yb(1)-Ni(1) bond lengths are 2.99 Å. All Yb(1)-Cu(1) bond lengths are 2.86 Å. Ni(1) is bonded in a 16-coordinate geometry to four equivalent Yb(1) and twelve equivalent Cu(1) atoms. All Ni(1)-Cu(1) bond lengths are 2.86 Å. 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. There are three shorter (2.42 Å) and three longer (2.45 Å) Cu(1)-Cu(1) bond lengths.
