K2YCd is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two K2YCd clusters. There are two inequivalent K sites. In the first K site, K(1) is bonded in a linear geometry to one Y(1) and one Cd(1) atom. The K(1)-Y(1) bond length is 3.16 Å. The K(1)-Cd(1) bond length is 3.38 Å. In the second K site, K(2) is bonded in a single-bond geometry to one Y(1) atom. The K(2)-Y(1) bond length is 2.05 Å. Y(1) is bonded in a distorted linear geometry to one K(1) and one K(2) atom. Cd(1) is bonded in a single-bond geometry to one K(1) atom.
