Ankita Puri: Copper, nickel and palladium complexes bearing bidentate redox-active ligands with tunable H-bond donors and acceptors.

In this study, we explore the structure and spectroscopic properties of a family of copper, nickel and palladium complexes bearing bidentate redox-active ligands that contain H-bonding donor and H-bonding acceptor groups. Single crystal X-ray crystallography shows intramolecular H-bonding interactions between the two ligand scaffolds can be finely tuned by different factors including metal center, ligand substitution, solvent of crystallization as well as counterion of the metal complex. Interestingly, the ability to control the intramolecular H-bonding interaction forces the complexes to adopt a certain geometry which can eventually permit to control the reactivity and catalytic performance of these complexes.
