LaYLaCu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one LaCu cluster and one LaY cluster. In the LaCu cluster, La(2) is bonded in a single-bond geometry to one Cu(1) atom. The La(2)-Cu(1) bond length is 1.11 Å. Cu(1) is bonded in a single-bond geometry to one La(2) atom. In the LaY cluster, La(1) is bonded in a distorted single-bond geometry to one Y(1) atom. The La(1)-Y(1) bond length is 1.67 Å. Y(1) is bonded in a 1-coordinate geometry to one La(1) atom.
