A series of platinum(II) complexes with the 2,5-bis(α-pyridyl)pyrrolate (PDP) ligand were synthesized. The ligand (X) trans to the central pyrrole nitrogen of PDP was found to play a key role in whether tridentate monomeric or bidentate clamshell dimer complexes were formed. When X = CH3or C6H5, strong σ-donor ligands, only dimeric clamshell structures were observed. In contrast, when X = Cl or I, ligands with π-donor properties, both dimeric and monomeric complexes could be prepared. The ability of the ligand framework to support monomeric complexes with π-donor X-type ligands is attributed to the PDP ligand’s ability to act as a competent π-acid in the monomeric conformation.
