La2TaPt crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one La2TaPt cluster. There are two inequivalent La sites. In the first La site, La(1) is bonded in a single-bond geometry to one Ta(1) and one Pt(1) atom. The La(1)-Ta(1) bond length is 1.21 Å. The La(1)-Pt(1) bond length is 0.56 Å. In the second La site, La(2) is bonded in a single-bond geometry to one Ta(1) atom. The La(2)-Ta(1) bond length is 0.85 Å. Ta(1) is bonded in a 3-coordinate geometry to one La(1), one La(2), and one Pt(1) atom. The Ta(1)-Pt(1) bond length is 1.17 Å. Pt(1) is bonded in a distorted single-bond geometry to one La(1) and one Ta(1) atom.
