La La Hf Sn
La2HfSn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one La2HfSn cluster. There are two inequivalent La sites. In the first La site, La(1) is bonded in a distorted bent 120 degrees geometry to one La(2) and one Sn(1) atom. The La(1)-La(2) bond length is 1.20 Å. The La(1)-Sn(1) bond length is 2.49 Å. In the second La site, La(2) is bonded in a distorted single-bond geometry to one La(1) atom. Hf(1) is bonded in a 1-coordinate geometry to one Sn(1) atom. The Hf(1)-Sn(1) bond length is 2.70 Å. Sn(1) is bonded in a 2-coordinate geometry to one La(1) and one Hf(1) atom.
