Abstract

Bond, metal-metal bond: Addition of 2.5 equiv of Li(N=CtBu₂) to MCl₂ (M=Mn, Fe, and Co), followed by addition of [12]crown-4, results in formation of [Li([12]crown-4)₂][M₂(N=CtBu ₂)₅] in good yields. These complexes exhibit short M-M distances and strong magnetic communication between metal centers, thus demonstrating that ketimides are viable co-ligands for promoting metal-metal bonding.
