K2YW is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2YW clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a linear geometry to one K(2) and one Y(1) atom. The K(1)-K(2) bond length is 0.43 Å. The K(1)-Y(1) bond length is 1.09 Å. In the second K site, K(2) is bonded in a single-bond geometry to one K(1) atom. Y(1) is bonded in a linear geometry to one K(1) and one W(1) atom. The Y(1)-W(1) bond length is 0.93 Å. W(1) is bonded in a single-bond geometry to one Y(1) atom.
