K Y Zn Zn
ZnKYZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two potassium;zinc molecules and two YZn clusters. In each YZn cluster, Y(1) is bonded in a single-bond geometry to one Zn(2) atom. The Y(1)-Zn(2) bond length is 1.15 Å. Zn(2) is bonded in a single-bond geometry to one Y(1) atom.
