Li Zn Zn Cu
LiCu(Zn)2 is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two copper lithium molecules and two Zn clusters. In each Zn cluster, there are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to one Zn(2) atom. The Zn(1)-Zn(2) bond length is 0.67 Å. In the second Zn site, Zn(2) is bonded in a single-bond geometry to one Zn(1) atom.
