Effect of the Carboxylate Shift on the Reactivity of Zinc Complexes in the Gas Phase

Abstract

The effect of different modes of the carboxylato ligands on the reactivity of gaseous zinc-acetate complexes is investigated by infrared multiphoton dissociation spectroscopy. In [(Imi)nZn(CH3COO)]+ complexes (Imi = imidazole, n = 1-3) the coordination changes from bi- to monodentate upon coordination of the third imidazole ligand ("carboxylate shift").
