Stable and metastable self-assembled rings based on trans-chelated Pd II
In contrast to the large number of self-assembled ring and cage structures based on cis-chelated square-planar metal complexes as connecting nodes, the use of trans-chelated square-planar building blocks is vastly underrepresented in supramolecular coordination chemistry. We here report of a strategy for the formation of self-assembled ring structures based on the trans-chelating ligand 1, 2-bis(2-pyridylethinyl)-benzene coordinated to PdII in a 1:1 fashion and bis-monodentate pyridyl bridging ligands. Depending on the angle between the two N-donor functionalities of the bridging ligands, three- or two-membered rings are quantitatively formed in solution. Whereas the former species show a high thermodynamic stability, the latter rings are of only kinetic stability if the bridging ligand is also able to form a coordination cage as an alternative product. The assembly and transformation of the supramolecular structures was characterized by 1H NMR spectroscopy and high-resolution FTICR-ESI mass spectrometry, augmented by semiempiric PM6 geometry optimizations.
