La2PtSb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two La2PtSb 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) and one Sb(1) atom. The La(1)-Pt(1) bond length is 1.90 Å. The La(1)-Sb(1) bond length is 0.45 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 1.90 Å. Pt(1) is bonded in a 3-coordinate geometry to one La(1), one La(2), and one Sb(1) atom. The Pt(1)-Sb(1) bond length is 1.91 Å. Sb(1) is bonded in a single-bond geometry to one La(1) and one Pt(1) atom.
