Li4SrZn is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Li4SrZn clusters. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one Li(2), two equivalent Li(1), and one Sr(1) atom. The Li(1)-Li(2) bond length is 0.81 Å. Both Li(1)-Li(1) bond lengths are 0.47 Å. The Li(1)-Sr(1) bond length is 0.38 Å. In the second Li site, Li(2) is bonded in a single-bond geometry to three equivalent Li(1) and one Zn(1) atom. The Li(2)-Zn(1) bond length is 0.34 Å. Sr(1) is bonded in a 3-coordinate geometry to three equivalent Li(1) atoms. Zn(1) is bonded in a single-bond geometry to one Li(2) atom.
