The Pd(II) ion in the title complex, [PdI(2)(C(10)H(9)N(3))], is four-coordinated in a distorted square-planar environment defined by the two pyridine N atoms of the chelating di-2-pyridyl-amine (dpa) ligand and two I(-) anions. The dpa ligand is not planar, the dihedral angle between the pyridine rings being 51.2 (2)°. In the crystal, pairs of complex mol-ecules are assembled through inter-molecular N-H⋯I hydrogen bonds into dimeric species. The complexes are stacked in columns along the b axis and display several inter-molecular π-π inter-actions between the pyridine rings, with a shortest ring centroid-centroid distance of 3.957 (3) Å.
标题配合物[PdI₂(C₁₀H₉N₃)]中的Pd(II)离子在由螯合二-2-吡啶胺（dpa）配体的两个吡啶N原子和两个I⁻阴离子所定义的扭曲平面正方形环境中呈四配位。dpa配体不是平面的，吡啶环之间的二面角为51.2 (2)°。在晶体中，配合物分子对通过分子间N-H⋯I氢键组装成二聚体物种。这些配合物沿b轴堆积成列，并在吡啶环之间显示出几种分子间π-π相互作用，最短的环心距为3.957 (3) Å。
