The results show that the title compound is stable, the geometry calculated by AM1 is in good agreement with experimental results. The atoms of O(1),O(15), O(19),O(20) in the molecule bond easily with metallic atoms. So the title compound can form stable complex with rare earth metal ions.展开更多

文摘The structure and coordination properties of N,N bis(N methylene 2 pyrrolidinyl)alanine have been studied. The results show that the title compound is stable, the geometry calculated by AM1 is in good agreement with experimental results. The atoms of O(1),O(15), O(19),O(20) in the molecule bond easily with metallic atoms. So the title compound can form stable complex with rare earth metal ions.
