The title compound, [PdCl2(C4H4N2)2], contains two crystallographically unique complexes; the PdII atom lies on an inversion center in both cases. The two pyridazine units bonded to the PdII atom are thus coplanar although dihedral angles within each complex are different. In one complex, the angle between the ring plane and Pd-Cl bond is almost perpendicular [89.4 (1)°], while the other is tilted with an angle of 60.0 (1)°. In the crystal, weak CH-N hydrogen bonds and CH-Cl interactions connect the two independent complex molecules.
