K Cd As As
KCdAs2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KCdAs2 clusters. K(1) is bonded in a single-bond geometry to one Cd(1) and one As(2) atom. The K(1)-Cd(1) bond length is 0.54 Å. The K(1)-As(2) bond length is 2.92 Å. Cd(1) is bonded in a single-bond geometry to one K(1) atom. There are two inequivalent As sites. In the first As site, As(1) is bonded in a single-bond geometry to one As(2) atom. The As(1)-As(2) bond length is 2.67 Å. In the second As site, As(2) is bonded in a distorted linear geometry to one K(1) and one As(1) atom.
