Effect of the linker length and amide group orientation on chiral bpa complexes of Zn(II) and Cu(II)
Bis(2-picolyl)amine (bpa) and its derivatives are tridentate ligands known for the formation of complexes with late transition metals that found use as enzyme mimics, metal ion sensors and anticancer agents. In the Cambridge Structural Database, a variety of bpa complexes are described, such as monomers, dimers and coordination polymers. In this work, six chiral bpa ligands and their complexes with Zn(II) and Cu(II) were prepared and characterized by NMR, UV-Vis and CD spectroscopy. The stoichiometry, stereochemistry and possibility of different hydrogen bonding patterns were studied by DFT calculations. To optimize the formation of ML2 complexes, several variations were introduced into the ligand structure, such as the length of the CH2 linker, orientation of the amide group (-CO-NH- or -NH-CO-) and different chiral substituents. In ML2 complexes, the ligands have the possibility of forming one or two intramolecular hydrogen bonds. In these hydrogen bonded secondary structures, transfer of chirality by ''backdoor induction'' to the metal centre is possible and such complexes could selectively catalyse enantioselective reactions.
