New coordination compounds, namely, zinc(II) dioxalatopalladate tetrahydrate [{Zn(H2O)3(Pd(C2O4)2)}2(μ-H2O)2]·4H2O and manganese(II) dioxalatopalladate monohydrate {(μ-C2O4)Pd(μ-C2O4)Mn(H2O)3}n·μH2O are synthesized. The compounds are characterized by IR spectroscopy, elemental analysis, and single crystal X-ray diffraction.

The complexes crystallize in different structural motifs: an oligomer in the case of Zn and a chain in the case of Mn. In both structures, oxalatopalladate(II) is coordinated by terminal oxygen atoms to the base metal.
