• New coordination compounds, namely, zinc(II) dioxalatopalladate tetrahydrate [{Zn(H 2 O) 3 (Pd(C 2 O 4 ) 2 )} 2 (μ-H 2 O) 2 ]·4H 2 O and manganese(II) dioxalatopalladate monohydrate {(μ-C 2 O 4 )Pd(μ-C 2 O 4 )Mn(H 2 O) 3 } n ·μH 2 O are synthesized. The compounds are characterized by IR spectroscopy, elemental analysis, and single crystal X-ray diffraction. The crystallographic data for the complex with Zn are as follows: a = 7.2812(4) Å, b = 9.0258(5) Å, c = 10.2468(6) Å, a = 81.0335(1)°, β = 80.5341(2)°, γ = 75.9627(1)°, space group 1 ¯ , Z = 2, ρ cafc = 2.367 g/cm 3 . The crystallographic data for the complex with Mn are as follows: a = 6.3605(4) Å, b = 8.8464(5) Å, c = 18.7382(1) Å, β = 98.398(2)°, space group P 2 1 / c, Z = 2, ρ calc = 2.607 g/cm 3 . 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.
