Na2LiZn is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Na2LiZn clusters. Na(1) is bonded in a distorted single-bond geometry to one Li(1) atom. The Na(1)-Li(1) bond length is 1.39 Å. Li(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Zn(1) atom. The Li(1)-Zn(1) bond length is 1.99 Å. Zn(1) is bonded in a distorted single-bond geometry to one Li(1) atom.
