PtTlGa2 crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one PtTlGa2 cluster. Pt(1) is bonded in a single-bond geometry to one Tl(1) and one Ga(1) atom. The Pt(1)-Tl(1) bond length is 0.78 Å. The Pt(1)-Ga(1) bond length is 2.76 Å. Tl(1) is bonded in a single-bond geometry to one Pt(1) atom. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted linear geometry to one Pt(1) and one Ga(2) atom. The Ga(1)-Ga(2) bond length is 1.26 Å. In the second Ga site, Ga(2) is bonded in a single-bond geometry to one Ga(1) atom.
