(Di-2-pyridylamine-κ2N2,N2′)diiodidopalladium(II)

The PdII ion in the title complex, [PdI2(C10H9N3)], is four-coordinated in a distorted square-planar environment defined by the two pyridine N atoms of the chelating di-2-pyridylamine (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 molecules are assembled through intermolecular N—H...I hydrogen bonds into dimeric species. The complexes are stacked in columns along the b axis and display several intermolecular π–π interactions between the pyridine rings, with a shortest ring centroid–centroid distance of 3.957 (3) Å
