Lu3Pt crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two Lu3Pt clusters. There are three inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 1-coordinate geometry to one Pt(1) atom. The Lu(1)-Pt(1) bond length is 2.34 Å. In the second Lu site, Lu(2) is bonded in a single-bond geometry to one Lu(3) atom. The Lu(2)-Lu(3) bond length is 0.57 Å. In the third Lu site, Lu(3) is bonded in a bent 150 degrees geometry to one Lu(2) and one Pt(1) atom. The Lu(3)-Pt(1) bond length is 2.19 Å. Pt(1) is bonded in a 2-coordinate geometry to one Lu(1) and one Lu(3) atom.
