YMgCu4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Y(1) and twelve equivalent Cu(1) atoms. Y(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1) and twelve equivalent Cu(1) atoms. Cu(1) is bonded to three equivalent Mg(1), three equivalent Y(1), and six equivalent Cu(1) atoms to form a mixture of edge, corner, and face-sharing CuY3Mg3Cu6 cuboctahedra.
YMgCu4 is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Mg(1) is bonded in a 16-coordinate geometry to four equivalent Y(1) and twelve equivalent Cu(1) atoms. All Mg(1)-Y(1) bond lengths are 3.10 Å. All Mg(1)-Cu(1) bond lengths are 2.97 Å. Y(1) is bonded in a 16-coordinate geometry to four equivalent Mg(1) and twelve equivalent Cu(1) atoms. All Y(1)-Cu(1) bond lengths are 2.97 Å. Cu(1) is bonded to three equivalent Mg(1), three equivalent Y(1), and six equivalent Cu(1) atoms to form a mixture of edge, corner, and face-sharing CuY3Mg3Cu6 cuboctahedra. There are three shorter (2.51 Å) and three longer (2.56 Å) Cu(1)-Cu(1) bond lengths.
