Coordination chemistry of carboxamide ‘Nx’ ligands to metal ions for bio-inspired catalysis

Deprotonated carboxamidate ‘N’ donors have been extensively explored as ligands to support metal ions with unusual higher oxidation states. Their ability to serve as both σ and π-electron donor, being resistant to oxidation and provide exceptional hydrolytic stability to a coordinated metal ion has altogether enhanced the broad applicability of carboxamidate ligands in bio-mimetic catalysis. Although the biological precedents with such class of...
