The title compound, [Pd2{P(C10H7)2(C10H6)}2Cl2]·2CH2Cl2, shows cyclometalation of one naphthalen-1-yl substituent of each of the phosphane ligands to the Pd dimer in a trans orientation; the complete dimer is generated by a centre of inversion. Two dichloromethane solvent molecules create C-H...Cl interactions with the metal complex, generating supermolecular layers in the ab plane. Additional C-H...[pi] and [pi]-[pi] [centroid-centroid distances = 3.713 (3), 3.850 (4) and 3.926 (3) Å] interactions join these planes into a three-dimensional supermolecular network.
