| Progress was made towards synthesizing an asymmetrical tetradentate pyridine N-oxide ligand (L). Pyridine N-oxide analogues of salen-type ligands are not very common, but few have been reported recently. We are now attempting to synthesize the first “hybrid” which should combine properties of salen-type ligands and their pyridine N-oxide analogs. The ligand was made through a series of condensation reactions. First a tridentate ligand was prepared by a condensation reaction by o-phenylenediamine with 2-pyridine N-oxide carbaldehyde. In the second step, the synthesized tridentate ligand was reacted with salicylaldehyde. A templated synthesis was employed to avoid substitution of the pyridine N-oxide with salicylaldehyde. Complexes of both new ligands, the intermediate tridentate ligand and the final tetradentate ligand (L), with first row transition metals were prepared and characterized using spectroscopic and diffraction methods.
