PtZnSb2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PtZnSb2 cluster. Pt(1) is bonded in a distorted single-bond geometry to one Zn(1) atom. The Pt(1)-Zn(1) bond length is 2.03 Å. Zn(1) is bonded in a 2-coordinate geometry to one Pt(1) and one Sb(1) atom. The Zn(1)-Sb(1) bond length is 1.32 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a single-bond geometry to one Zn(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 1.94 Å. In the second Sb site, Sb(2) is bonded in a 1-coordinate geometry to one Sb(1) atom.
