KLaZn2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KLaZn2 clusters. K(1) is bonded in a trigonal non-coplanar geometry to one La(1) and two equivalent Zn(1) atoms. The K(1)-La(1) bond length is 0.57 Å. Both K(1)-Zn(1) bond lengths are 1.55 Å. La(1) is bonded in a single-bond geometry to one K(1) atom. Zn(1) is bonded in a single-bond geometry to one K(1) atom.
