镧系杂环胺三元配合物从６０ 年代起至今已有丰富研究，而镧系四元混合阴离子配合物近来引起了一些研究者关注。镧系元素与苯甲酸及其衍生物和邻菲?啉（ｐｈｅｎ）形成的混配配合物具有多种形式的分子构型及配位多面体，结构变化甚多，它们的四元配合物的结构变化则更加丰富，因此此类配合物能为我们提供更多的信息。由于该类配合物有二个含芳香环的配体，因此配合物中可以考察芳环堆积效应。我们探索合成了新的配合物［Ｃｅ（ｐ－ＭＢＡ）２ （ＮＯ３）（ｐｈｅｎ）］２，并解析了配合物的晶体结构 Lanthanide heterocyclic amine ternary complexes have been extensively studied since the 1960s, while lanthanide quaternary mixed anion complexes have recently attracted the attention of some researchers. Mixed complexes of lanthanides with benzoic acid and its derivatives and phenanthroline (phen) have a variety of molecular configurations and coordination polyhedrons with many structural changes. The structures of their quaternary complexes Changes are richer, so these complexes give us more information. Since there are two aromatic ring-containing ligands for these complexes, the aromatic ring packing effect can be examined in the complexes. We explored the synthesis of a new complex [Ce (p-MBA) 2 (NO3) (phen)] 2, and resolved the crystal structure of the complex
