Di-μ-chlorido-bis­({8-[bis­(naphthalen-1-yl)phosphan­yl]naphthalen-1-yl-κ(2) C (1),P}palladium(II)) dichloro­methane disolvate

The title compound, [Pd(2){P(C(10)H(7))(2)(C(10)H(6))}(2)Cl(2)]·2CH(2)Cl(2), 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⋯π and π–π [centroid–centroid distances = 3.713 (3), 3.850 (4) and 3.926 (3) Å] inter­actions join these planes into a three-dimensional supermolecular network.
