WCo4 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one WCo4 cluster. W(1) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), one Co(3), and one Co(4) atom. The W(1)-Co(1) bond length is 1.85 Å. The W(1)-Co(2) bond length is 1.56 Å. The W(1)-Co(3) bond length is 1.47 Å. The W(1)-Co(4) bond length is 1.09 Å. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded in a 1-coordinate geometry to one W(1) atom. In the second Co site, Co(2) is bonded in a distorted single-bond geometry to one W(1) atom. In the third Co site, Co(3) is bonded in a single-bond geometry to one W(1) atom. In the fourth Co site, Co(4) is bonded in a single-bond geometry to one W(1) atom.
