La La Hf Zn
La2HfZn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2HfZn clusters. La(1) is bonded in a 2-coordinate geometry to one Hf(1) and one Zn(1) atom. The La(1)-Hf(1) bond length is 1.43 Å. The La(1)-Zn(1) bond length is 1.43 Å. Hf(1) is bonded in a 3-coordinate geometry to two equivalent La(1) and one Zn(1) atom. The Hf(1)-Zn(1) bond length is 1.63 Å. Zn(1) is bonded in a 3-coordinate geometry to two equivalent La(1) and one Hf(1) atom.
