As part of our attempts to prepare FeIII complexes with "tunable" spin states, we have synthesized three novel six-coordinate FeIII complexes containing both carboxamido nitrogen (Namido) and phenolato oxygen (Ophen) donors in their ligand framework. Since it has already been shown that carboxamido nitrogen donors usually stabilize FeIII in a low spin configuration, while phenolato oxygens tend to stabilize FeIII in a high spin state, we have incorporated both donor groups in our designed ligands. The syntheses and structures of FeIII complexes with either one or two Namido and Ophen donors are reported in this paper. The properties of these complexes have been compared with the properties of analogous FeIII complexes. The competing effects of Namido and Ophen on the spin state of the FeIII center are discussed in terms of the stabilities of the overall complexes.
