While bidentate beta-diketiminate (BDI) ligands are prominent in coordination chemistry, the chemistry of tetradentate BDI ligands is relatively unexplored. To this end, a series of tetradentate N2P2 ligands has been synthesized by appending phenyl linkers with pendant phosphines donors on a β-diketiminate backbone. The ligand 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 different binding modes as well as the synthesis and characterization of these first-row transition metal complexes will be discussed.
