摘要：

A series of complexes formed by the interaction of UO2 (AcO)2.2H2O and some potentially bidentate ligands, aniline, o-hydroxy, o-carboxy, o-chloro, o-methoxy and o-methylaniline-7- carboxaldehyde-8- hydroxyquinoline abbreviated as HL1, H2L2, H2L3, HL4, HL5 and HL6, respectively, have been synthesized. The products were characterized by elemental analyses, magnetic moments and spectral measurements. All the ligands behave as monobasic bidentate chelating agents coordinating to the uranium(VI) ion via the deprotonated phenolic OH and aldehydic oxygen and/or azomethine nitrogen. Thermal stabilities of the ligands and complexes have been studied using thermogravimetric analysis (TGA).
