In the title complex, [PdCl₂(C₁₃H₉N)₂], the Pd^II ion is four-coordinated in an essentially square-planar environment by two N atoms from two acridine ligands and two Cl^- anions. The Pd atom is located on an inversion centre, and thus the asymmetric unit contains one half of the complex and the PdN₂Cl₂ unit is exactly planar. The dihedral angle between the PdN₂Cl₂ unit and the acridine ligand is 84.66 (6)°. In the crystal, the complex molecules are stacked in columns along the a axis connected by C-HCl hydrogen bonds, forming chains along [110]. In the columns, numerous intermolecular [pi] - [pi] interactions between the six-membered rings are present, the shortest ring centroid-centroid distance being 3.722 (4) Å.
