PtZnTl2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PtZnTl2 clusters. Pt(1) is bonded in a distorted single-bond geometry to one Zn(1) and two equivalent Tl(1) atoms. The Pt(1)-Zn(1) bond length is 0.34 Å. Both Pt(1)-Tl(1) bond lengths are 1.66 Å. Zn(1) is bonded in a single-bond geometry to one Pt(1) atom. Tl(1) is bonded in a single-bond geometry to one Pt(1) atom.
