Pd2Ge is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pd2Ge clusters. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to one Pd(2) atom. The Pd(1)-Pd(2) bond length is 0.53 Å. In the second Pd site, Pd(2) is bonded in a linear geometry to one Pd(1) and one Ge(1) atom. The Pd(2)-Ge(1) bond length is 1.51 Å. Ge(1) is bonded in a single-bond geometry to one Pd(2) atom.
