摘要
采用分步法,首先合成了新的多齿Schiff碱配体N,N′-双(2-吡啶甲醛亚胺基乙基)-2,6-吡啶二甲酰胺(Ⅱa),进一步合成了10个新的稀土金属配合物,再通过元素分析、红外光谱、紫外光谱、质谱及核磁共振等测试手段对配体及配合物进行了表征,并对配合物进行了合理的结构推测.
In this paper,we took fractional steps to synthesize linear multidentate Schiff base ligand [N,N′-bis(2-pyridinyl-iminoethyl)-2,6-pyridinedicarboxylic diamide(Ⅱa)] firstly,and then 10 rare earth mental complexes linked by Schiff base.The ligand and complexes are characterized by elemental analysis,IR,UV,MS and 1H NMR,and also the rational structures of them are speculated.
