WCo2Cu crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two WCo2Cu clusters. 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 1.57 Å. The W(1)-Co(2) bond length is 1.57 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted single-bond geometry to one W(1) and one Cu(1) atom. The Co(1)-Cu(1) bond length is 2.11 Å. In the second Co site, Co(2) is bonded in a single-bond geometry to one W(1) atom. Cu(1) is bonded in a distorted single-bond geometry to one Co(1) atom.
