In the title compound, [PdCl2(C21H21O3P)2], the Pd atom adopts a slightly distorted square-planar coordination geometry, with pairs of the equivalent ligands in cis positions. Adjacent molecules are linked by weak C—H⋯Cl hydrogen bonds. The crystal structure is additionally stabilized by π–π stacking interactions between the aromatic rings [shortest centroid–centroid distance = 3.758 (4) Å].
The structure of the title compound was determined as part of a larger study on palladium(II) complexes with triphenylphosphito ligands.
