1H NMR STUDIES ON THE LANTHANIDE COMPLEXES OF TRIPODAL LIGAND
摘要
Abstract
The preparation of binary and ternary solid complexes of lanthanide ions with tripodal ligand N,N-bis(2-benzimidazolylmethyl)-N-(2-pyridylmethyl)amine (L) and antipyrine (L′) is reported in this article. The coordination forms of the complexes in various solutions were studied by 1H NMR, supported by the single crystal x-ray diffraction and IR data, as well as the ab initio calculation. In CH3CN solution, L coordinates to the metal atoms with four nitrogen atoms, while L′ with its carbonyl oxygen only. The coordination numbers of the binary and ternary complexes were 10 and 7 respectively. In the ternary complexes, anions and solvent molecules could not enter the coordination sphere due to the steric effect of three big L′ molecules. The complexes dissociate in the strongly polar DMSO solution.关键词
