Abstract
This review focusses on noncovalent metal ion-ligand complexes and measurem ents of the bond energies of such species. The method utilized in this work is threshold collision-induced dissociation (CID), as achieved using a gui ded ion beam tandem mass spectrometer. Accurate determination of bond energ ies requires attention to marry details of the experiments and data analysi s, These details are discussed thoroughly and compared to over methods. A c omprehensive listing of metal-ligand bond dissociation energies determined by threshold CID is provided. This list includes a variety of metals (alkal is, magnesium, aluminium, and first and second row transition metals), many different types of ligands, and variations in the number of ligand's. The trends in these values are discussed, and we elucidate the importance of io n-dipole and ion-induced dipole interactions chelation, different conformer s and tautomers, steric interactions, solvation phenomena, and electronic e ffects such as hybridization and promotion.
