A family of tetradentate N2P2 ligands has been synthesized as flexible ligands for transition metals. The ligand has been created by appending phenyl linkers with pendant phosphines donors on a β-diketiminate backbone. It features both hard and soft donors in an attempt to create an ideal environment for first-row transition metals of varying oxidation states. To understand the binding modes of the ligand with first-row transition metals, substituents have been introduced at different positions on the phenyl linkers. The ligands were previously metallated with zinc(II) iodide and showed two different binding modes based on the presence of the methyl group on carbon 6 of the phenyl linker. Its chemistry has been extended to Co(II), Ni(II) and Cu(I) metals. The synthesis and characterization of these late first-row transition metals complexes will be discussed.
