In the title complex, [PdCl₂(C₁₆H₁₂N₂)], the Pd^II ion is coordinated by two N atoms [Pd-N 2.039 (2), 2.073 (2) Å] from a bidentate ligand and two chloride anions [Pd-Cl 2.2655 (7), 2.2991 (7) Å] in a distorted square-planar geometry. In the crystal, [pi] - [pi] interactions between the six-membered rings of the quinoline fragments [centroid-centroid distances = 3.815 (5), 3.824 (5) Å] link two molecules into centrosymmetric dimers.
