(W)2W2Co is alpha carbon monoxide-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two tungsten molecules and two W2Co clusters. In each W2Co cluster, there are two inequivalent W sites. In the first W site, W(2) is bonded in a single-bond geometry to one Co(1) atom. The W(2)-Co(1) bond length is 2.45 Å. In the second W site, W(3) is bonded in a single-bond geometry to one Co(1) atom. The W(3)-Co(1) bond length is 0.48 Å. Co(1) is bonded in a distorted single-bond geometry to one W(2) and one W(3) atom.
