Abstract
Abstract Palladium(II) has four coordination sites and forms square planar complexes. Discrete self-assemblies are generated by the combination of a variety of palladium(II) components and ligands ranging from bi- to polydentate. The Pd(II) components used are generally of two varieties: cis -protected Pd(II) and unprotected Pd(II). Most common cis -protecting units (X-X) such as ethylenediamine, 2,2′-bipyridine and 1,3-bis(diphenylphosphino)propane and a few other related chelating systems have been exploited for the complexation reactions. The self-assemblies formed are generally represented as [{ cis -Pd(X-X)} x ( L ) y ](monoanion) 2 x and [Pd m ( L ) n ](monoanion) 2 m when generated from the complexation of a suitable ligand ( L ) with cis -protected Pd(II) and simple Pd(II) units, respectively. When Pd(solvent) 2 Cl 2 is complexed with ligands, the solvent molecules are replaced with the incoming ligands, leading to complexes in which the trans positions are occupied by the chloride anions.
