Li Li Li Li Pt Pt
Li2Pt crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Li2Pt cluster. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 3-coordinate geometry to one Li(1), one Li(2), and one Pt(1) atom. The Li(1)-Li(1) bond length is 1.12 Å. The Li(1)-Li(2) bond length is 0.61 Å. The Li(1)-Pt(1) bond length is 0.65 Å. In the second Li site, Li(2) is bonded in a 2-coordinate geometry to one Li(1) and one Pt(1) atom. The Li(2)-Pt(1) bond length is 0.49 Å. Pt(1) is bonded in a 2-coordinate geometry to one Li(1) and one Li(2) atom.
