(Di-2-pyridyl-amine-κ(2)N(2),N(2'))diiodidopalladium(II).

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.
