摘要
二元配合物ErL-3(L=吲哚-3-乙酸,吲哚-3-丙酸,吲哚-3-丁酸)中,羧基的两个氧原子与Er(Ⅲ)双齿配位.三元配合物ErL3· phen中,3个配体吲哚酸分子有部分(1或2个吲哚酸分子)以双齿配位,其它吲哚酸分子以 单齿配位.吲哚环中的氮原子未参加配位,邻菲G86AA啉分子中的两个氮原子参加配位.
Binary complexes ErL 3[L:indole 3 acetic acid(IAA) ,indole 3 propanic acid(IPA) and indole 3 butanic acid(IBA)]of the melecules are coordinat to Er(Ⅲ) ion in a bidentate fashion through carboxylic oxygen at oms.In ternary complexes some of the three IAA(or IPA,IBA)melecules are found to be coordinating to Er(Ⅲ) ion in a monodentate fashion through carboxylic oxyge n atoms,while the others are coordinating to Er(Ⅲ) ion in a bidentate fashion t hrough the carboxylic oxygen atoms.The nitrogen atom in the indole ring has not interacted with Er(Ⅲ) ion at all,but the two nitrogen atoms in 1,10 phenanthro line are coordinating to Er(Ⅲ) ion.
