• The effect of different modes of the carboxylato ligands on the reactivity of gaseous zinc−acetate complexes is reported. Using infrared multiphoton dissociation spectroscopy, it is demonstrated that the coordination of acetate in [(Imi) n Zn(CH3COO)]+ complexes (Imi = imidazole, n = 1−3) changes from bi- to monodentate upon coordination of the third imidazole ligand. This so-called carboxylate shift substantially influences the reactivity of the zinc−acetate complexes in comparison to complexes with monodentate counterions. The differences in reactivities are demonstrated on the ligand exchange reactions of [L n ZnX]+ (n = 2 or 3,; L = imidazole or pyridine; X = OH, Cl, CH3COO, and CH3CONHO).
