Understanding the molecular and electronic structure of transition metal complexes is important for utilizing their catalytic and redox properties. Our group has been examining the coordination chemistry and subsequent reactivity of transition metal complexes with amidinate and salicylaldiminate ligands. Recently, we have synthesized the dicuprous complex, Cu2(2,6-dimethylphenyl-formamidinate)2, and have been exploring its reaction with I2. Reaction in THF produces a complex with a bridging triiodide, Cu2(amid)2(THF)2(�-I3) while the product in toluene is a trinuclear species, Cu3(amid)3(I2). Both complexes are mixed-valent Cu2+/1+. I will also present our preliminary results with first row transition metal salicylaldiminate ligands demonstrating structural and reactivity differences between the 2,6-dimethyphenyl and 2,6-diisopropylphenyl derivatives.
