Al2CoV crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Al2CoV cluster. V(1) is bonded in a single-bond geometry to one Co(1) and one Al(1) atom. The V(1)-Co(1) bond length is 0.37 Å. The V(1)-Al(1) bond length is 0.95 Å. Co(1) is bonded in a 3-coordinate geometry to one V(1), one Al(1), and one Al(2) atom. The Co(1)-Al(1) bond length is 1.00 Å. The Co(1)-Al(2) bond length is 0.88 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 3-coordinate geometry to one V(1), one Co(1), and one Al(2) atom. The Al(1)-Al(2) bond length is 1.08 Å. In the second Al site, Al(2) is bonded in a distorted single-bond geometry to one Co(1) and one Al(1) atom.
