摘要：

We report the results of a potentiometric study on the formation of weak complexes between imidazole (im) and acetate, malonate, and citrate (L), at T = 25-degrees-C. Formation of protonated species H(j) (im)(L), in which j = 1 for acetate, j = 1, 2 for malonate and j = 1, 2, 3 for citrate, was found. The formation of weak complexes between N-ligands and O-ligands may be used to interpret the behavior of these classes of compounds in natural fluid and/or in biological systems, as regards inter- or intra-molecular interactions.
