KV2W crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KV2W clusters. K(1) is bonded in a distorted single-bond geometry to one W(1) atom. The K(1)-W(1) bond length is 1.88 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 2-coordinate geometry to one V(2) and one W(1) atom. The V(1)-V(2) bond length is 1.22 Å. The V(1)-W(1) bond length is 2.23 Å. In the second V site, V(2) is bonded in a 2-coordinate geometry to one V(1) and one W(1) atom. The V(2)-W(1) bond length is 2.39 Å. W(1) is bonded in a distorted single-bond geometry to one K(1), one V(1), and one V(2) atom.
