In the title compound, [PdCl(2)(C(21)H(21)O(3)P)(2)], the Pd atom adopts a slightly distorted square-planar coordination geometry, with pairs of the equivalent ligands in cis positions. Adjacent mol-ecules are linked by weak C-H⋯Cl hydrogen bonds. The crystal structure is additionally stabilized by π-π stacking inter-actions between the aromatic rings [shortest centroid-centroid distance = 3.758 (4) Å].
