Li2ZnSb is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Li2ZnSb clusters. Li(1) is bonded in a 3-coordinate geometry to one Li(1), one Zn(1), and one Sb(1) atom. The Li(1)-Li(1) bond length is 0.31 Å. The Li(1)-Zn(1) bond length is 0.50 Å. The Li(1)-Sb(1) bond length is 0.50 Å. Zn(1) is bonded in a 3-coordinate geometry to two equivalent Li(1) and one Sb(1) atom. The Zn(1)-Sb(1) bond length is 0.31 Å. Sb(1) is bonded in a 3-coordinate geometry to two equivalent Li(1) and one Zn(1) atom.
