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 总被引:3,自引:0,他引:3
The new solid complexes [LnL2(NO3)2]NO3 (L=C18H23NO2, N-2-hydroxy-3-methoxy-benzaldehyde-1-aminoadamanantane, Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y) of rare earth nitrates with Schiff base derived from o-vanillin and adamantaneamine have been synthesized in non-aqueous system and characterized by elemental analysis, molar conductance, infrared spectra, 1H NMR spectra, thermal analysis. The coordination modes of the bonding in these complexes were discussed and the possible structure were proposed. Every central Ln(Ⅲ) ion 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 their four oxygen atoms. Their coordination numbers are eight. In addition, the antibacterial activity of the Schiff base ligand and the complexes were studied. 相似文献

Th(Ⅳ)、U(Ⅵ)金刚烷胺Schiff碱配合物的合成、表征及抗菌活性 总被引:2,自引:0,他引:2
由金刚烷胺缩水杨醛Sch iff碱配体(C17H21NO,以HL1表示)和金刚烷胺缩邻香兰素Sch iff碱配体(C18H23NO2,以HL2表示)分别与UO2(Ac)2.2H2O和Th(NO3)4.4H2O作用,合成了四种新的配合物(1)[UO2(Ac)2(HL1)4].1.5H2O,(2)[UO2(Ac)2(HL2)].1.5H2O,(3)[Th(NO3)4(HL1)2].H2O,(4)[Th(NO3)4(HL2)2].H2O.用元素分析、摩尔电导、红外光谱和热重分析进行表征;并对所合成的配合物在DMF中进行了抗菌活性的初步测定,研究表明铀(Ⅵ)配合物有一定的抗菌活性,而钍(Ⅳ)配合物则无抗菌活性. 相似文献
