La La La Pt
La3Pt crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La3Pt clusters. There are two inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one Pt(1) atom. The La(1)-Pt(1) bond length is 1.29 Å. In the second La site, La(2) is bonded in a single-bond geometry to one Pt(1) atom. The La(2)-Pt(1) bond length is 2.47 Å. Pt(1) is bonded in a 2-coordinate geometry to one La(2) and two equivalent La(1) atoms.
