YVCu2 is Copper structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one YVCu2 cluster. Y(1) is bonded in a distorted single-bond geometry to one Cu(1) and one Cu(2) atom. The Y(1)-Cu(1) bond length is 0.51 Å. The Y(1)-Cu(2) bond length is 1.14 Å. V(1) is bonded in a 1-coordinate geometry to one Cu(2) atom. The V(1)-Cu(2) bond length is 1.36 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one Y(1) atom. In the second Cu site, Cu(2) is bonded in a 2-coordinate geometry to one Y(1) and one V(1) atom.
