La La Zn Fe
La2FeZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2FeZn clusters. There are two inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one Zn(1) atom. The La(1)-Zn(1) bond length is 1.51 Å. In the second La site, La(2) is bonded in a 2-coordinate geometry to one Fe(1) and one Zn(1) atom. The La(2)-Fe(1) bond length is 1.25 Å. The La(2)-Zn(1) bond length is 1.51 Å. Fe(1) is bonded in a 2-coordinate geometry to one La(2) and one Zn(1) atom. The Fe(1)-Zn(1) bond length is 1.41 Å. Zn(1) is bonded in a 3-coordinate geometry to one La(1), one La(2), and one Fe(1) atom.
