LaSc4Cu crystallizes in the trigonal R3m space group. La(1) is bonded in a distorted single-bond geometry to three equivalent Sc(1) and one Cu(1) atom. All La(1)-Sc(1) bond lengths are 1.59 Å. The La(1)-Cu(1) bond length is 1.83 Å. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 5-coordinate geometry to one La(1), one Sc(2), two equivalent Sc(1), and one Cu(1) atom. The Sc(1)-Sc(2) bond length is 1.30 Å. Both Sc(1)-Sc(1) bond lengths are 0.75 Å. The Sc(1)-Cu(1) bond length is 3.41 Å. In the second Sc site, Sc(2) is bonded in a 3-coordinate geometry to three equivalent Sc(1) atoms. Cu(1) is bonded in a single-bond geometry to one La(1) and three equivalent Sc(1) atoms.
