La La Pt Pt Pt Pt
LaPt2 is diamond structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of two LaPt2 clusters. La(1) is bonded in a distorted L-shaped geometry to one Pt(1) and one Pt(2) atom. The La(1)-Pt(1) bond length is 1.10 Å. The La(1)-Pt(2) bond length is 1.32 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one La(1) atom. In the second Pt site, Pt(2) is bonded in a distorted single-bond geometry to one La(1) atom.
