WCo2Al crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WCo2Al clusters. W(1) is bonded in a 1-coordinate geometry to one Co(1) and one Al(1) atom. The W(1)-Co(1) bond length is 2.10 Å. The W(1)-Al(1) bond length is 1.44 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a single-bond geometry to one W(1) atom. In the second Co site, Co(2) is bonded in a single-bond geometry to one Al(1) atom. The Co(2)-Al(1) bond length is 1.12 Å. Al(1) is bonded in a 2-coordinate geometry to one W(1) and one Co(2) atom.
