稀土与杂环胺双齿配体络合物的研究始于60年代,但有关三氯醋酸稀土与邻菲绕啉(phen)络合物的研究仅有少量的报道。本文通过先制得稀土三氯醋酸盐,再与phen反应的方法,合成了14种三氯醋酸稀土与邻菲绕啉的络合物,避免了氯离子可能参与络合和配体间可能发生酸碱缔合等副反应,并研究了络合物的组成和性质。 Studies on rare earth and heterocyclic amine bidentate ligand complexes began in the 1960s, but only a few reports on the studies of rare earth trichloroacetate and phenanthroline complexes have been reported. In this paper, we firstly synthesized rare earth trichloroacetate and then reacted with phen to synthesize 14 complexes of rare earth trichloroacetate and phenanthroline to avoid the possibility of chloride ion participating in the complexation and possible ligand-ligand interaction Acid-base association and other side reactions, and studied the composition and properties of the complex.
