Zn Cu Cu Pd
PdCu2Zn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two PdCu2Zn clusters. Pd(1) is bonded in a distorted linear geometry to one Cu(1) and one Cu(2) atom. The Pd(1)-Cu(1) bond length is 2.54 Å. The Pd(1)-Cu(2) bond length is 2.54 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted single-bond geometry to one Pd(1) atom. In the second Cu site, Cu(2) is bonded in a single-bond geometry to one Pd(1) and one Zn(1) atom. The Cu(2)-Zn(1) bond length is 0.17 Å. Zn(1) is bonded in a single-bond geometry to one Cu(2) atom.
