Pd2Zn crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one Pd2Zn cluster. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to one Zn(1) atom. The Pd(1)-Zn(1) bond length is 0.49 Å. In the second Pd site, Pd(2) is bonded in a distorted water-like geometry to one Pd(2) and one Zn(1) atom. The Pd(2)-Pd(2) bond length is 1.38 Å. The Pd(2)-Zn(1) bond length is 1.44 Å. Zn(1) is bonded in a distorted linear geometry to one Pd(1) and one Pd(2) atom.
