W3Co2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W3Co2 clusters. There are two inequivalent W sites. In the first W site, W(1) is bonded in a linear geometry to one Co(1) and one Co(2) atom. The W(1)-Co(1) bond length is 1.77 Å. The W(1)-Co(2) bond length is 1.23 Å. In the second W site, W(2,3) is bonded in a single-bond geometry to one Co(2) atom. The W(2,3)-Co(2) bond length is 1.45 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a linear geometry to one W(1) and one W(2,3) atom. The Co(1)-W(2,3) bond length is 1.45 Å. In the second Co site, Co(2) is bonded in a linear geometry to one W(1) and one W(2,3) atom.
