Li Li Zn Cu
Li2CuZn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Li2CuZn cluster. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 1-coordinate geometry to one Li(2) atom. The Li(1)-Li(2) bond length is 0.89 Å. In the second Li site, Li(2) is bonded in a distorted L-shaped geometry to one Li(1) and one Cu(1) atom. The Li(2)-Cu(1) bond length is 1.86 Å. Cu(1) is bonded in a 2-coordinate geometry to one Li(2) and one Zn(1) atom. The Cu(1)-Zn(1) bond length is 1.62 Å. Zn(1) is bonded in a 1-coordinate geometry to one Cu(1) atom.
