金刚烷胺邻香兰素Schiff碱稀土配合物的合成、表征及抗菌活性研究

The new solid complexes [LnL2(NO3)2]NO3 (L=C18H23NO2, N-2-hydroxy-3-me thoxy-benzaldehyde-1-aminoadamanantane, Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, H o, Er, Tm, Yb, Lu, Y) of rare earth nitrates with Schiff base derived from o-van illin and adamantaneamine have been synthesized in non-aqueous system and charac terized by elemental analysis, molar conductance, infrared spectra, 1H NMR spect ra, thermal analysis. The coordination modes of the bonding in these complexes w ere discussed and the possible structure were proposed. Every central Ln(III) io n in the complexes coordinates with both two Schiff base ligands via four oxygen atoms of the phenol hydroxy groups and methoxy groups and two nitrates via thei r four oxygen atoms. Their coordination numbers are eight. In addition, the anti bacterial activity of the Schiff base ligand and the complexes were studied.
